I have a user losing all network access at 4pm everyday. She is running Vista buisiness. Server is SBS2008 and all other users are unaffected by this.
there are these errors in event viewer of the SBS:
DCOM was unable to communicate with the computer <user-pc>.local using any of the configured protocols.
I left it running a ping -t during the period. It was all fine until this ocurred where it went to "Request Timed Out". tried restarting the NS on both the SBS and the user-pc. disabled and re-enabled the network adaptor on the user-pc.
