over the past couple days, we’ve seen XP sp2 workstations having periodic drive mapping problems. Drive mappings are made to dfs shares at logon. during the day, these mappings suddenly become unavailable. the drive letter is still there but when opening the drive, an error appears saying it is unavailable. Rebooting, unmapping and remapping or doing a “check status” of the dfs link restores access. the only change is that the servers hosting the dfs shares (w2k3 sp1) were rebooted after installing some MS patches.
Does anyone know of a registry or gpo setting that a ms patch may have changed regarding this or a way to set a setting to increase the frequency where the client will refresh or check status of connections to dfs shares.
