TL;DR: Unable to map a network drive on one particular computer, except if circumventing DFS.
OK - So I have exhausted all my options in this matter, so all suggestions are welcome.
Keep in mind the file system is DFS.
1. User has been set up the same as our other users in Active Directory.
2. Most network drives are connected via GPO. They are mapped via\\company.local\common\
3. The users' home folder is connected via setting in AD -> Profile -> Home folder ->
Connect X: To \\company.local\homedir\username
4. When the user logs on, all network drives defined in GPO are mapped OK, but the X: which is defined via "Home folder" in AD, is not connected. When trying to map it manually, we get "Access denied".
5. If the user tries the complete path via Explorer: \\company.local\homedir\username - Error 0x80004005 Unspecified error occurs. We have googled this particular code but found nothing that applies to us.
6. If the user tries the complete path to the folder on the actual file server, circumventing DFS, the home folder is mapped OK.
Strange thing is: This only happens on this particular computer. If users logs on to another computer, in the same domain, receiving the same GPO etc. The X: is mapped fine via \\company.local\homedir\username
Also if another user logs on to the problematic computer they also cannot access their X: on \\company.local\homedir\username
So we tried updating the WLAN/LAN drivers to no avail. Might there be any settings on the network adapters that might cause this?
