That is an old Win 98 problem, nutcrusher, but that file usually goes missing along with VREDIR.VXD and MSNP32.DLL. If that is the same for you and beeuuem's suuggestion doesn't work, the usual way to fix the problem (I've had to do it a number of times on Win98 machines), is to remove Client for Microsoft Network from Control Panel > Network (if I remember correctly) then reinstall it again. Re-booting in between.
I've never had this problem myself (touching wood!) Looking in Google did throw up the scenario you describe, though I didn't find an answer to the problem. Just in case, I have made a note of your solution -thanks. B
There is an answer to it on Google somewhere. I found the solution by trial and error about 18 months ago, then came across the solution on Google a while after that, while looking for something else (isn't always the way?). I was pleasantly surprised and not unchuffed when I did find it, but if I had to go back to the article, I couldn't. I know I should have taken note of the site at the time and I can't say why I didn't. Nought out of ten for forward planning, eh?
