yes, your correct, this only happens when connecting remotly. It looks like the credential manager is having some problems. But I didn't find any solution yet.
Security Warning Credential dialog box hidden

When using an RDP connection or opening a admin share the security warning dialog box gets hidden and we need to wait 5 minutes before the dialog box appears. This happens everytime a security warning needs to pop-up. Whe already did a sfc /scannow, the DISM option, etc. What could cause this problem?
