Dear Sirs: In job I've been using the following servers: SERVER1 is a NT4.0-SP4 as PDC for one domain, SERVER2 was a Mandrake 8.0 based box with samba 2.not remember now version, sharing some folders for extra disk space for the users (over 200 Windows 98). This was set up at user security level. Both were working so fine. From any of the clients, when I clicked on Network Neighborhood, I watched a list of all the clients, and both servers. Last week we had an infection with NIMDA virus. SERVER1 was affected seriously, so we decided to duplicate the users from SERVER1 to SERVER2 and duplicate the personals shared resources to the equivalents home directories. We switched off SERVER1 from the network, and set up SERVER2 to be at domain security level and accepting logons, changed the name to SERVER1, and restarted the samba daemons. Again so fine. The users can log on, we were unmo The problem now is with the clients. If we try to watch the Network Neighborhood now we get and error saying that the network is not avalaible. What is more curious is that if we write, for example, in the explorer bar \\SERVER1 we get again the error pop up message, but, THE SHARED RESOURCES ARE SHOWN!! I don't know how to solve this problem (I'm almost newbie with samba). Suggestions?? Thanks in advance!!
