Finally i must install ePO 4.5 Patch 4 and successful to deploy agent through workgroup. In ePO 4.6 that can not (don't know why). Thanks All!
Have you tried connecting to the machines in question from the epo server itself?
i.e. \\machinename\admin$ using the credentials of the local machine? If you can't connect then the ePO server cannnot as well.
The Admin$ must be shared.
NetBios over TCP/IP must be enabled
And ports 135 and 139 must be open through the Firewall.
Now i can deploy by ePO 45 Patch 4. But in ePO 46 i can not browse computers (Failed to enumerate domains, authentication required) so can not deploy agent. Thanks!
