Hey Everyone -
One of the more tech savy clients of mine decided to install Hamachi on his SBS 2003 server. It was restarted last night for updates and now all the workstations are unable to log into the domain. I came in and first looked in the DNS settings and found that there had been a new record for the server under the Hamachi address. I removed it, restarted the server, and uninstalled Hamachi, but am still facing issues with connectivity with the clients. Also, Exchange Server is also unavailable as well.
As I connect the workstations I see in the IPCONFIG status, that the DNS record points to our router rather than the SBS Server. The only way I've seen to change it is to manually add the record in the TCP/IP settings.
