Thanks for your reply.
I checked that, and it's using the default credentials used by the Adaxes services, and that account has domain admin credentials.
As soon as I launch the application, I get the Connecting to MYSERVER....Binding...
That window stays on for almost 5 minutes (I clocked it); then clicking on on any domain OU or object takes a very long time - longer than it used to take in the previous version. This seems to happen mainly on our management consoles.
When I run the management console from the server - the application runs much faster.
