BIG problems after upgrading to 11D

Hello.

 

We are using Backup Exec to backup multiple Windows servers in different domains and network.

All backups are directed to one media server.

 

Version used was 10D.

 

No Windows communication allowed, port 10000 - 10100 (opened in firewall, no changes before/after upgrade) used for all server <-> agent communication.

Accessing servers through "User-defined Selection".

 

Today we upgraded to Backup Exec 11D Rev 7170 with Service Pack 1, Hotfix 17, Hotfix 18, Hotfix 19, Hotfix 20 and Hotifx 21 (using LiveUpdate).

 

And this was a very very big mistake!

 

After the upgrade it takes minutes when clicking on a server in "User-defined Selection".

When starting a backup, it immediately gets "Queue" in Job Status.

If I leave it alone, the job will start to run after about 6-7 minutes.

 

 

 

Questions:

1) Are there any changes in communication regarding 10D vs 11D ?

2) Are there any other changes which could affect my systems  this way ?
