Windows 7: Problem - Network Access - Can't map drives, can't see any servers

23 Mar 2012   #1

Windows 7 Professional 64 bit
Problem - Network Access - Can't map drives, can't see any servers

I've got a ThinkPad x220 here and randomly started having issues accessing the network (mapped drives and printers). The computer can still access our Intranet (Sharepoint) and Exchange Server (Outlook says connected and we can send/receive)

I tried disconnecting the drives and reconnecting, but none of the servers were showing up in the list. I then checked to see if network discovery and file sharing were turned on... they were. Tried manually going to a network drive (i.e. the public drive \\public\ and no luck. I did some research and tried a list of things (even checked the local security policy settings) and still nothing.

I now have the computer disjoined from the domain and I was going to attempt to rejoin, but it wouldn't go. I get the prompt to type the domain username and password, but when I hit OK, it gives me an error and says domain cannot be reached. Something weird is going on with Network Discovery or file sharing... or something.

FYI - I have disabled Windows Firewall and uninstalled Symantec Endpoint Protection.

I am going to try safe mode with networking now... If I have no luck with that, I'm probably just going to do a clean install.

Before you do that, Check your WIFI and/or communications drivers on the thinkpad first.

I had a workstation on my network do this recently. Turns out the driver for the Broadcom Ethernet adapter went all wonky.
