Long loading times/customer search during network installation
Error description
If a user without administrator rights starts the GP Manager, the connection is slow. The GP Manager may take several minutes to search. If the user is logged in as an administrator or domain administrator, the GP Manager responds normally quickly.
Cause of error
Windows 10 caches files from the network. Unfortunately, it seems that in some configurations the permissions for the file location are not set correctly. This can be traced if you use the Process Monitor from Microsoft and monitor the GpManager.exe process (https://docs.microsoft.com/en-us/sysinternals/downloads/procmon).
Troubleshooting
The easiest way is to deactivate the cache for network shares in the registry. Here is a summary and a link to the article from Microsoft:
In the registry you can create three DWORD values under the path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\Parameters
According to the article, these should be deactivated in the following order in the event of problems:
- Directory cache, by setting DirectoryCacheLifetime to ZERO.
- File Not Found cache, by setting FileNotFoundCacheLifetime to ZERO.
- File information cache, by setting FileInfoCacheLifetime to ZERO.
