I am the network administrator for a large company and run a large WAN with about 15 NT servers. I have been doing this job as well as a PC tech for about 4 years. I have worked with all windows OSes extencively and done an extencive amount of troubleshooting and installing with them. In short, I believe I am very capible and have a extencive knowledge of current operating systems. I have been working with computers since I have been very young and work on them a lot in my spare time as well.
Now I am looking at getting the MCSE certification for windows 2000 and the related Items. Should I go somewhere for courses or should I get a self study kit? Will I find the exams challenging at all? I am not totally familiar with Win2k but use it fairly aften. Active directory is still a mystery to me bu I am sure I would figure it out in a few minutes of playing around. What do you people thiink? Give me some advice please!
