#199 7zip in Citrix Environment

[CTX1]

We want to use 7zip within our citrix (PS4.5) environment
But within 7zip users have access to the whole server. We already blocked access to the server drives by GPO, but it seems 7zip isn't impressed with that ;) All other applications can't access the local server drives, only 7zip can.

How can we prevent this?

Thanks
