Ok, I'll start at the beginning.
I had an issue where a new user couldn't install software (windows installer), the error message they get is;
Error 1324. the path My Documents contains an invalid character.
I've also seen a similar message which I havn't got to hand which goes something like;
the <username> is not a valid short name.
Right, my documents has been redirected for all users to one of our file servers. After lot's of reading, I have nothing. I've done lot's of testing too and come up with something. If I make the user in question a local admin of the file server storing my documents, he can install with no errors.
So this leads me to the file server and permissions on that. They have full control to my documents and I tried giving him full control to the share but no joy. I've also looked at the local security policy and given them rights to any objects that seemed could be remotely relevant (like by traverse checking, backup files and directories etc) yes, clutching at straws here.
The answer has to be within the rights on the file server but I just can see what. Can anybody give me a clue on where I should be looking next. I naturally don't want to give them admin rights to the file server, nor do I want to do what the previous admins have done which is add them to domain admins :)
Oh, windows 2003 R2 SP2 servers Windows 2003 AD domain in mixed (I think)
