I have an SBS 2008 server that was migrated from SBS 2003.
This issue started showing up a day after the SBS 2003 was completely removed from the domain and the migration finished.
At different times during the day, when all users are logged in, the network will get very slow, the SBS 2008 will quit responding to file requests, and new logins will time out with the "The system cannon log you on due to the following error: The RPC service is unavailable."
Only a reboot will clear this issue.
I did not see this occur at all over the weekend when there were only a couple of users logged on.
Once the SBS 2008 has been rebooted there are no issues.
