Exclude Dir from Roaming TS Profile

Hello,

I have the following problem with our new 2008 R2 Ts Server, When i use a surtain webapp it sets a file in my Temporary Internet Files. The file name is to long to copy when i logof and the server try's copy my roaming profile back to the server where the Profiles are stored.

I allready setup an gpo to Exclude this folder (Appdata\local\Microsoft\Windows\Temporary Internet Files) and also in the registry the key in the folder "HKEY_CURRENT_USER>Software>Policies>Microsoft>Windows>System" is pressent.

But the problem keeps existing, does someone have an solution for this problem?

With kind regards,

Rick de Jong
