I have a system with server 2003 on a network with several XP PRO workstations and 3 Windows 98 stations. The system had not been updated for a while, and after the last 17 updates installed, the server is no longer visible on the network. Programs that run from the server are working, but you cannot map a drive to a server share from a workstation from within Windows. Net Use from a command prompt works for some, but not all shares.
The Three Windows 98 machines can no longer log on. The error message is no DNS server found.
Symantec Enterprise version 10.0 gives a message "no windows 2000/xp/2003 machines were detected in the selected work group or domain" when I try do a remote install from the system console.
The router has been changed from an old GVC to a netgear, but all seems fine at that end. It appears that the server is being prevented from being viewed on the network, and the 98 machines cannot see the server at all.
