This is really bugging us. We have a simple workgroup with server 2003 and a few shares. 9 or so computers could connect to a mapped drive no problem yesterday. About mid day 4 of the machines lost connection. We've researched and tried a number of fixes to no avail.
We can connect to the server using \\server ip address and we do receive a \\computername\username and password challenge but none of the known good users or passwords allow us to actually log in. We can connect and log in using RDP from machines in question using the server IP but not the server name.
We cannot connect using \\server name\share and we get an error message. Additionally the server does not show in network places and cannot be found when browsing for a drive. All other machines on the network are visible to the machines that cannot access the server share so we don't think it's a switch routing issue (also because we are prompted to login when using server Ip)
We have: verified NetBIOS, restarted computer browser, set lm & ntlm, turned off offline file sync, checked for hidden in registry and flushed the dns cache all without resolution.
We have not been able to restart the server as there are users actively connected.
Any suggestions will be greatly appreciated.
