When I browse "My Network Places", I can see both mine and my girlfriends PC - same for my girlfriend when she browses "Network Neighbourhood".

The problem is that while I can connect to her PC, she can't connect to mine. When she tries, she gets a "Workgroup" messagebox which says "The network is busy". (?!)

2 pcs. Mine is running Win2ksp2, My girlfriends is running Win98se (I know, I know). We are sharing a cable broadband connection using a wired Belkin router, and our IP addresses are DHCP assigned (from the router). We both have valid IP addresses within the range specified in router control panel. We're using TCP/IP. The connection speed is reported as 100Mbps. Both network cards support this speed (mine is an old Intel card and I bought a new Linksys card for my girlfriend's PC earlier today). Duplex mode is set to auto-detect on both cards.

We are both members of the same workgroup (called "workgroup"). There is no network name as such - I initially set one up through the router, but have now turned it off to try and overcome this prob. The Win98 machine has got File and Print Sharing enabled, and primary logon is via "Client for MS Networks". My PC has the "File & Print Sharing" installed.

We originally both had firewall software, but this is now disabled - the router takes care of that. I recently re-started a few Win2k services, and now the PCs can actually see each other (they couldn't until quite recently). Which services need to be running for home networking?

Various ipconfig /renew and winipcfg /renew and various reboots haven't sorted it.

I'm stumped :-( Anyone got any ideas?
