I have a lot of workstations having troubles

Unable to communicate with ZESService. Please make sure that ZES Service is running.

I've found TID: 7012847 and it looks like i have the case2.

I did fix it doing a unr -f and reregister with -g option and then clearing directory c:\programdata\novell\zes\store\service and then restart service ZESSERVICE. (With an administrator account)

Doing this for all other workstations takes a lot of time.

Is there a fix for this issue in 11.24?? Or a fix i could deploy in the meanwhile?
