Servers not scanned

[Arie]

I have installed Lansweeper 3.5 with the premium tools and enabled active scanning. Now only two of my server are scanned and are displayed in de database. Has anyone got an idea why this is. Am I missing something

Could you please post your errorlog.txt file please.

All are other workstations scanned normally?
If yes then you just have to wait, servers and DC's don't report to logon servers that often (some workstations report every 15 minutes)
