Option 2. Installation only for domain1. It is necessary to perform installation with domain administrator's rights.
2. Make sure that shared folder admin$ is actually shared on the remote computer. In most cases there is no need to do anything but shared access has to be performed on the remote computer:
net share admin$
3. "Remote registry" service must be enabled on the remote computer.
4. It is important to make sure the domain administrator is not deleted from local administrators list on the remote computer (see "Computer management"->"Local users and groups"->"Administrators" on the remote computer)
Attention! Sometimes some antivirus software on clients' computers can block this installation option.
