[RESOLVED] Windows 98 Logon problem

[The Phoenix]

I got a bunch of computers from a local school at an auction, and I chose the best one to add to my home network and such.

Its a NEC, Pentium III 866MHz, 6gig HDD, 256mb RAM, Windows 98 machine. I wa playing around with it, getting all the old School-related stuff off, and such. Then I wanted to get it set up to connect to my router, so I tried to add a new network adapter. (Note: This is the first time I've ever done this. I understand the theories, but my implementation may be wrong.)

After I did that last night and shut it down, I tried to reboot this morning and it stops me at the logon screen. I had a user name and password that worked before, but now it doesn't, plus there's now a "Domain" field that wasn't there before.

One of the things I did in my tweaking was change the Computer's name, because it was still named "Chem Lab 1" or something.

I've tried to get into safemode so I can edit the users or something, but F8 doesn't so anything, it just continues on to Windows...

Any ideas?
