On a recent project I had to work with a remote team of designer.
The company provided me with the VPN client configuration and read/write access to a shared folder on one of their servers.
Everything went fine until I started assigning the master data directories within Eplan P8. I kept getting error messages saying that I didn’t have access to those folders. We checked with the IT team, and they assured me the rights were properly set.
It turns out that for some reason, if you use UNC notation, ie \\server\path\to\folder, then Eplan seems to want to have access rights to each folder within the path, which was not the case here. I only had access rights to the deepest directory.
The problem can be easily solved by using a mapped letter drive in Windows that is mapped to the deepest directory, and then use that drive letter in Eplan.
