I have a very odd problem. I believe someone was messing with our Group Policy and the following problem now exists:
When a XP wireless notebook goes into standby mode and it brought back to life and tries to reconnect to the domain, everything connects fine except for browsing to a single domain controller's shares. If you browse using the domain controllers IP address all the shares appear. Also, if you browse using the syntax "\\domaincontroller." (adding a period) the share show, but they will NOT show by just browsing to "\\domaincontroller".
