RCMD and other issues

[Guest ITGuy]

We have a computer that started out with a problem logging into an Intranet

site of ours. The user on that machine only gets an error and this site uses

windows authentication to logon automatically. Anyway, another possibly

related issue is that the ability to RCMD to the machine does not work

either. We have tried to drop the machine from the domain and rejoin and it

seems to work for 5-10 minutes and then it goes back to the same problems.

You also cannot access the event viewer, services, etc. remotely through an

MMC. Other things like logging in and using exchange email works for the user

though. Any ideas on what could fix this issue? Thanks in advance!
