Handshake on Modem but unable to establish connection

Hi guys and gals,

Customer called and said modem won't connect. Said fine bring it in. Tried it, does the 'hand shake' but right after trying to verify the username and password, it says can't establish a connection. I tried my password, does the same. I replaced the modem with two different ones, same problem.

Removed all protocols and reinstalled again.
Extracted a new copy of all winsock files and replaced the old ones. Even upgraded IE5 to IE 5.5 but no go. Any suggestions?

Internal or external (USB or serial) modem?

Sorry, it is a Creative Modem Blaster ISA. (Less than a year old).

My personal thought is that it is not the modem since I tried the two other modems (different brands).

I have sold a lot of these Creative Modems and never (literally) never had a problem. I like the stability and compatibility of the old ISA architecture. (Call me old school)

you didn't mention the OS but if it's 98SE hit the MS site for a newer version of DUN

I tried going to the MS website using support.microsoft.com as well as corporate.windowsupdate.microsoft.com but still was unable to find a version of DUN.

Can anyone point me to the right link?

Thanks in advance.

This may sound obvious, but make sure you've got "Dial-up Adapter" showing in your network properties.

Go here and select the version you need.


------------------
Boy, I'm tired of being right.

Tried the DUN idea, but that didn't work. There is a handshake, it gets to verify username and password, and then it either just sits there for ever, or disconnects and tells me that it was unable to establish a connection.

I am running Norton's virusscan on it to be on the safe side.

Any other ideas guys? I really appreciate all your help. https://forums.windrivers.com/

try lowering the modem connection speed
try lowering the transmit and receive buffers
make sure client for microsoft networks is installed and dialup adapter are installed, I'm sure you've already checked it....just going with things off the top of my head...

Does it ever verify the password and username? If not make sure you got the right one. Also some passwords might be case sensitive. Make sure you follow your ISP's instructions to a tee. Sometimes it's something that doesn't make any sense but it works. *sigh* don't you just love computers?

Boy, I'm tired of being right.

FYI: Just to be on the safe side, I ran Norton AV on her harddrive. No virus or anything malicious. I did notice drvspace.bin on her harddrive. Then I noticed she had compressed her harddrive. IT is a freaking 30GIG harddrive. Who the hell compressed a 30Gig HDD????????????

Lusers....

Short of reloading win98 on their, any other suggestions. TIA

Shoot the user????

Sorry I'm a little sarcastic today. It sounds like an ISP problem. Either the username / password is having issues or you could be having problems with the authenticating device on the other end. I'm pretty sure that if you send a good logon to the authenticating server and the server never responds you could get a disconnected notice.
I have also run into problems where the modem was trying to transfer faster than the other side could receive. Turning the connection speed down works in Win98, NT but something to do with Win2k "optimization" over rides a manual connection setting...
Good Luck!

------------------
The truth is out there, you just need to decrypt it.

I hate diagnosing modems, I'll try to help

Install Hypertermnal.
Setup a connection but cancel it. right before it will dial the required phone number.

you should be at a terminal emulation window.

type atz <enter>
you should get an Ok
If you get the Ok then try ati9
replacing 9 with numbers 1 through 9 to check the modems firmware. (Some modems have more numbers.)

If that all goes well and you got phone 2 lines. try ata1 <enter> then setup another modem on another computer to call that machine to see if it connects.

If I rambled or was no help or was wrong, then oh well.

F-disk Reboot Format C: setup Windows

If you have removed and re-installed the dial up adapter, Client and TCP/IP Ran regclean at least 3 times,on the registry and still have issues, the registry may be corrupted, 98 you can run scanreg and that may fix it however; my expierience is at this point to "BLOW" off the OS after backing up all data and settings.

Heres some thing you can try, since the router firmware could of been updated it may be unable to connect now. go into the dun folder and hit the properties for the connection, and click on the configure button. where it says max speed, if its set to 115200 set it to 9600 (which disables compression) if it connects try setting the speed to 57600. If it connects at 9600 but unable to when you set it to 57600 update the drive and firmware for the modem. A initialization string is a thing of the past, but may be required. call your ISP to find out what type of digital modems they have at their end and the version of the firmware. If you need any other assistance feel free to email me [email protected]

Luke, OBGYN Kanobi is the only one!!

http://support.microsoft.com/support.../Q191/4/94.asp (MSDUN13)Also if you run regclean it may possibly screww up your Symantec products,old 3 year old bug I found and Symantec posted.I never did hear what OS it was,but sounds like Win95 or wWin95B (osr2). To verify ,go to my computer and then dialup networking and double click on the ISP attempting to connect too.It probably will work,Install MSDUN13.Also it is good idea to use Microsoft Network for "primary Logon server" and NOT family or windows logon. Also all you need is Microsoft Network,dial up adapter and TCP/IP,all of that other stuff in your case is junk. If you are using Win98/se use DUN40 .Anytime you need to find something and fast I personally use GOOGLE.COM. After you install the new DUN ,use the MS connection wizard to set your setting and in 95/B/C/D/E/F put 0.0.0.0.0 for the IP addressbecause almost every ISP automatically assign now a days.How this helps,if not you may contact me directly if you wish,solving tough dogs I thrive and live for.

I don't think your problem has to do with the IP stack. I think we need to focus on the modem itself. Somewhere in the '98 dialler you should find something which will cause the modem to log what it's doing (I don't have a '98 machine in front of me but I think you'll find a check box called "append to log". This will log all the interactions between the PC and the modem - the init string, the dial string and the responses. The one we're interested in is the "CONNECT" string - the one that TAPI takes as a cue to hand over the com port to the IP stack so that PPP can do its thing.
Now most modem manufacturers (probably at the instigation of MS) set the init string to that modem will say CONNECT or CONNECT + DTE speed the speed of the port to the computer, *not* the speed that the modem trained at. Whether the modem trained with error correction or not is left out also.
Why do we care about all this?
Because the speed of the carrier and whether we trained with error correction (preferably LAPM/ V42bis give us an idea as to how well the the modem trained. If it got a V90 full rate (56000bps) but no error correction, it may be too flakey to pass any useful data - like your PPP logon - without corrupting it.
So my advice - find your modem documentation, look out the string to get extended result codes, put it in the extra init string under advanced properties, and look to see whether it trained at full speed *and with error correction*.
If it looks (from the log) that it's having a hard time maintaining a connection the it's either the line or the modem. If it's the former you'll just have to slow down the speed. Sometimes modems can get training patterns over a line - they just can't make any data move over it.

I had the same problem today on a win95 osr2.5 box. I completely uninstalled dialup networking via the add/remove programs, restarted the pc, reinstalled dialup networking, restarted, tried again. Worked great. Thats only fixed problems like that for me twice. Just thought I would mention it. Good luck. https://forums.windrivers.com/

What does Device Manager show?
Any port or IRQ conflicts?
Also, is the drive still compressed?

This may sound quite dumb, but, humor me. call ISP and see if they have any odd username requirements. Back in the day I had a netcom account and would ony connect if I used the format [email protected] in the username feild of DUN. If I rember correctly I got the same error when it done any other way. Good Luck.

My two cents.Is the user name and password in the connection tab of internet explorer,under settings?And what isp is she using.Some are hard coded,some are given a ip adress automatically.If the modems dialing,it's not the modem.If you have doubt it is the modem,use the diag property in the modem section of the control panel.Check the telephony section while your there.Reinstall the isp in internet explorer in the connection tab under setup.And worse comes to worse,put the cd in and reinstall the os.Good luck

I've seen this happen many times...in fact just the other day... I too tried extracting a new copy of winsock.dll and wsock32.dll and it did not work... Even made sure all other modems and even the .inf files were gone through safe mode (you know ghosting). I knew I'd seen the problem many times before (when Win95 was new) but forgot the solution Doh! Anyway Murphy's law again...last thing to try works...

1) Remove DUN (Control Panel...Add/Remove Programs...Windows Setup...Communications...(uncheck Dial up Networking))

2) Restart Windows

3) Reinstall Dial up Networking then restart again...should do the trick...

If there is a network cable installed, then disable the modem and try again.

Also try re=install client for Microsoft networks if you have not done so already.

------------------
You never Know everything!!!!!

You have of course tried another ISP?

If it dials and squarks, you know for sure it ain't your modem, try connecting via the icon in dialup networking, see what that says is your non correction error, then look it up!

enter safe mode <quick way from windows - restart in dos, then at prompt - c:\windows>win /d:m

remove all evidence of modems, should be a few by now, also look for any serial mouse that may be the cause of the problem even if it shouldn't be installed - had that happen recently.

Check country settings are correct, connection will be much degraded - had that happen too.

You mention using Norton, I'm unclear if it was already installed, get rid of it...I have solved far too many modem connection issues by uninstalling Norton (2000, 2001). This app swamps dial-up connections. I had one customer who refused to allow me to ditch Norton even after several lengthy visits. She relented after the fourth visit, mildly hysterical (so was I, her half dead dog kept sneezing and farting on me). Immediate connection. I installed AVG and left with head held high, smelling like a skunk and covered in fluff.

Telecos have a page in their helpdesk manual that only contain the words `its a hardware fault'...first or second page in.

check out msconfig/startup as well, something may be loading that invokes rnaap.

Beware the Hybris virus too

You might try turning on modem logging and PPP logging, then try connecting, then open the logs and see if it gives you a clue as to why it's not connecting. At least maybe you will be able to refine your search...

In your dialup networking window rightclick on the dun and choose properties. on the modem settings click configure. Click the options tab. Check the box marked "bring up a terminal after dialing". ok everything and dial. This will bring up a terminal after dialing and allow you to log in manually. This may show you some information about the password handshake process you can't see otherwise. If you get nothing but garbage in the terminal then the modem just isn't negotiating with the ISP and I would blame the ISP at that point. There used to be a few ISP's in our area where this was the only way to log in, their password dialog was funky and always refused a login normally.

------------------
What's the differance between 'twisted' and 'torqued' anyways?

simple solution maybe, not alot of work.

Call the ISP. Check on their status. are they having problems, upgrading or such?

maybe already posted.

--------

More coffee any one

who are they trying to connect to ?
maybe a issue with winsock2
AOL messes up winsock2 really bad
this doesn't sound like a modem hardware issue
slow down the modem aswell with an AT command

Get another HDD with just win98SE on it and install the drivers for your clients computer. Try to connect and see if it works. If it does reinstall the OS on original HDD. If not yell at the ISP https://forums.windrivers.com/

Yet another tip.

In your Dial Up Adapter properties, look under the Bindings tab to make sure only TCP/IP is bound to it.

Remove any instances of NetBEUI, IPX/SPX and the like - and also remove them from the Server Types tab in your DUN properties.

What a pain to give some help. Had to register and both of my favorite usernames are already taken. Anyway:

Kind of glanced over the other replies but here's a couple of things that might help. Hopefully I'm not repeating anything already said.

One ISP here will not connect with Microsoft Family Logon installed. Don't know why, but installed, no connection. Removed Family Logon (nothing else) and it connects fine. Check to see if Microsoft Family Logon is installed in the Network Properties.

Another thing I've noticed with Norton, when you install it, it automatically sets itself to NOT check ALL files. Many of the new virus types (ie Kak worm) will not even be detected with this setting. When running a scan, I always go into Options and set Manual Scan options to all files and to conserve time not compressed files. If you find a virus, you may want to go back and do compressed files too, but with this option off it'll save you a ton of scan time. 'Sides, if the files are compressed, they aren't doing anything. Not too sure if the default settings with Norton even scan Winsock.dll.

I think you should focus on the networking and duns stack - This I think is also the Microsoft Family logon issue posted above.
I would blow away ALL network settings, close and let windows apply the files changes bu DO NOT reboot. Go back into network properties and re-add everything again. Whern you close out it will rebuild all files. Had this happen a ton of times with remote users. The next trick is to uninstall and reinstall duns from the add-remove windows componoents (like previously brought up). You should also post back here to let the other techs know what worked


------------------
them -... when I click on this it crashes.
me - OK, reboot and let's troublesho...
them - ...see, it did it again... me - sigh

After trying all of the above suggestions, I blew away windows. Tried installing it from the win98 directory (I did a deltree), and it still didn't help. Thought maybe the cab files were corrupt, so I ran setup from the CD and same thing.

Finally I contacted my friend FDISK, and he came over to help me out. I am also doing a low level format on the drive to make sure everything IS toast.

Will let you all know if that helps. Meanwhile, if you guys come up with something else, please post it here since I did make a backup before killing windows.

Thanks for all those who took the time to help me out.

A simple fix may be just to use
+MS=v34 in the modem settings to slow the modem down to V34. I've seen this a lot on the cheaper (HP & Compaq modems). If it says dialing for several seconds after the handshake ends and stops or gets to verifying username and password, stops for several seconds then disconnects.....Try it.

Hope this might help.... https://forums.windrivers.com/

If walking is so good for you, then why does my mailman look like Jabba The Hut?

Check the encryption on your password if you are dialing into a unix server

regards and best of luck

throw some different memory in it.

I've had some luck resolving DUN problems by completely removing the TCP/IP stack.

Error Message Occurs When You Run WINIPCFG at Microsoft Knowledge Base shows how to completely remove TCP/IP settings (registry included).
