Here's the error message I sometimes get when browsing a mapped network drive:
Z:\SomeFolder is not accessible.
The specified server cannot perform the requested operation.
Also some files just don't show up in explorer when browsing the mapped network drive. I know they are there because I can see and open them in explorer on the PC hosting the network share.
First some information: The network consists of a workgroup of two PC's (Tiger and nForce) both running Windows XP Professional 32 bit SP2. Both PC's have two NICs, 1-Gbit NICs with a direct cable between the two PCs (10.0.0.1 and 10.0.0.2) for fast Windows networking, and 100-Mbit NICs connected both to a port in a NAT router/switch for internet access (192.168.1.101 and 192.168.1.102, router 192.168.1.1).
The problem started after completely reinstalling Windows on the Tiger PC (with format of C). The reinstall was performed with only the C disk present. The other disks (F, G and H) were reconnected after the installation was complete. The problem occurs when mapping to shares on those drives. Shares created on the newly installed C drive don't give the problem.
After a lot of searching I've found what I think may be the cause, but unfortunately I still don't have a solution.
In the "Group or user names:" box on the security tab of the file property dialogue boxes of files that don't show in the mapped drive there is an unkown user named S-1-5-21 followed by four more cipher groups of length 10, 9, 10 and 4 separated by hyphens. This user has a different icon: a head with a red question mark in the lower right corner.
I think this user is a leftover from the previous Windows install.
When I select that user and click "Remove" I get "You cannot remove ... because this object is inheriting permissions from its parent. To remove ..., you must prevent this object from inheriting permissions, and then try removing ... again."
So I think I go to the parent object and remove this rogue user there. So I go to the highest folder in the hierarchy on that drive, click properties, and try to remove that user, but I get the same message. So I right-click the drive, choose properties etc., but there this unknown user doesn't show, so how can I remove him?
