Yes, and I don't know why, but how can this influence whether it is forbidden to chmod it? Note that I'm allowed to copy it and to remove it. Just chmod is disallowed. > Further > information would > be useful, such as the attached output of 'cygcheck -svr'; see > cygwin.com/problems.html.

Actually, *all* my files seem to have mkgroup_ as group - and this is true since the installation of Cygwin two years ago (and, no, I didn't have updated it since then). > your /etc/group file is probably out-of-date, so see the output of > 'mkgroup --help' to remedy that. Here is what mkgroup -lcu says: SYSTEM:S-1-5-18:18: None:S-1-5-21-602162358-162531612-725345543-513:513: Administrators:S-1-5-32-544:544:Local_Adm,fischron Backup Operators:S-1-5-32-551:551: Guests:S-1-5-32-546:546:Guest,Admin Power Users:S-1-5-32-547:547: Replicator:S-1-5-32-552:552: Users:S-1-5-32-545:545:ASPNET Debugger Users:S-1-5-21-602162358-162531612-725345543-1001:1001: mkgroup_l_d:S-1-5-21-2052111302-842925246-682003330-513:10513:fischron I wonder why the group is listed here as mkgroup_l_d and as mkgroup_ in the ls -l output. I therefore did a ls -ln on the files and see that the numeric group id of the files is given as 10513, which matches that of mkgroup_l_d. So I guess that ls -l just trims the group name to 8 characters, and that's why we see the strange group name "mkgroup_". > > I don't know about the 'stat' command you are refering to. > > It is part of coreutils-5.3.0-6.

Of course I will do if this is the only way, but I don't like upgrading if it is not strictly necessary. You know: "Never touch a running system". What stumbles me is that chmod ceased to work "overnight", so I was thinking what *does* happen overnight, and indeed, there is something going on: The backup of the network drives! In our machines, the C: drive is the local drive, while the other driveletters are mapped to network devices. I do most of my work on the network drives, but now I also checked /cygdrive/c/ ... and indeed, none of the file on the local C: drive posed any problems for chmod'ing them!!! This means, that the chmod problem seems to be related only to the Network. As a side note, a colleague of mine had also a problem with his files at about the same time, though not related to Cygwin: In the middle of the day, a couple of files simply had disappeared from his network drive (he was able to recover an old version from the backup). It's not clear whether this relates to the problem I'm experiencing, and I just want to include it for completeness. Ronald
