Creating update mirror hangs

Im using ERA server Ver. 4.0.138.11 on our W2k3 server. Since June 1 creating the update mirror hangs. If I got to server options in the ERA console on the update tab the update states NOD32 v2- mirror creating 50%.

What did I do so far:
Tried this: http://kb.eset.com/esetkb/index?page=content&id=SOLN2220&actp=search&viewlocale=en_US&searchid=1307342878612

I also unchecked the "create mirror for NOD32 v2" and deleted the v2-subfolder. Than again I chose "clear update cache" but the result is still the same.

Any ideas? Thanks.

 

Where are you creating the mirror? Do the Local System and Network Service accounts have the proper permissions on this folder?

 

The mirror is in a folder on the server. It worked for about 3 years now so I doubt there are probems with permissions. The problem started on June 1.

 

Restarting the ERA server service seems to have solved the problem.
