My user called and said he can not see the T drive. I checked and found the mapping to that specific drive letter was gone. I thought re-mapping would do it. But no, it didn't. Getting into My Network Places/Microsoft windows network/Domain Name, I was surprised to find this specific win2003 server just totally disappeared on the network. In Windows Explorer's address column, I typed \\Server's Name, it gave me an error address saying like "the specified network is no longer available...."
But the strange thing is, I was able to sucessfully ping the server's ip address or host name without any lost or delay.
That server is a Dell PE2900 2.66 Ghz quad core with 4 HDs on a raid 5 and is just a file sharing server without any other application loaded.
Can anyone tell me what could be wrong at that point?? -- even the server was up and running normally after a reboot.
