lansweeper3.5 - Active Scanning issue

[Geislinger]

Dear Support-Team,

since we have updated to 3.5 not all computers in the domain are found and I have absolutely no clue, why this happens.
Here the content of the errorlog.txt (just the last entries, because it's always the same):

Thank you for your fast response.

I installed the beta and it seems to find way more computers (maybe all, but I will wait a bit and have a look then) now....

Please try this update (beta) : http://www.lansweeper.com/forum/yaf_postst1514_Lansweeper-Service-351-update-1-beta.aspx
