I'm having major problems getting ZCM to deploy the ZAA to about 200 Windows XP SP2/SP3 devices using the .net agent. About 100 devices have successfully worked using the same method.
From the zen server, I can reach the admin share, ping both ways remote execute programs and am using the domain admin account to deploy the agent.
On the devices, there are errors in the event log from Zenworks Pre Agent saying malformed URl https://(zenserverFQDN):443/.......

Any help greatly appreciated!!!
