I have update my primary server, Windows 2008 SP2 from ZCM 10.3.0 (clean install) to ZCM 10.3.1 without errors, I have checked the components versions after the upgrade on the server:

ZENworks Configuration Management Version
ZENworks Asset Management Version
ZENworks Patch Management Version
ZENworks Agent Version
Package Name: CASA.msi Version: 1.7.1613
Package Name: authtokenclient.msi Version: 1.7.1630

I do an upgrade of a Windows XP SP3 device from 10.3.0 to 10.3.1, and check that the components versions are ok, the same as the primary server.

I have checked the event viewer on the server and I found this error twice during the updgrade: Product: ZENworks User Management -- A newer version already exists

On the Windows XP SP3 client no error found on event viewer.

The problem is that, when I try to login to the Windows XP SP3 device is much slower than before, around 3 or 4 minutes.

I have read these two TID 7006481 and 7006646 but not luck.

Can anyone help me?
