These computers are out of domain. DNS shouldn't have impact on that.
I see that there two reason of this problem. After restart GUID I've lost configuration:
- Computer Client License,
- Computer Backup Destination,
- Computer Image Job.
In order to eliminate the lack of license I need to restart the job on the server (SSR-MS) and the services on client computer (in services.msc).
In order to eliminate the lack of Backup Destination and Image Job we need to wait for time when job is starting.
Now it' ok.
I still doesn't know how two clients computers have the same GUID. But it's common problem in SSR-MS I see because there are many articles.
I look once again into the article: http://www.symantec.com/business/support/index?page=content&id=HOWTO6538 and found the link to article applies to Altiris 7.1 GUID clean up:
http://www.symantec.com/business/support/index?page=content&id=TECH212345 In this article there are more link to another script to detecting this problem and another script to prevent the GUID problem.
I run the first one and find another problems in my system. I will run the script to delete this GUID problem and will observe the results.
