RE: [ActiveDir] XP can't see PDC

[Za Vue]

I have a server that is assigned all the W2K AD roles, RID, Infrast.,PDC, GC, etc. It also houses 90% of the user data. Some Windows XP machines cannot access the shares from time to time. You can't event ping the server when this happens. It does not happen all the time.  The other 2 servers in AD never have the problem. A reboot of the server normally fixes the problem. Not a lot of activities in the log files, nothing out of the ordinary.   Thanks in advance for any thought/solution.   Thank you, Za
