Hi @all,

when i deploy ZCM Agent on Windows XP Service Pack 2 Clients they do not register.
If i try to register with zac i get this message:
"RegistrationManager - Connection error:
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."

When i install XP SP3 it works !

Here is the System we use:
ZCM 10.1 on Windows 2003 EE SP2 on ESX
external Certs
external Oracle DB

I also tried with a test Server System:
ZMC 10.1 on Windows 2003 EE SP2 (IBM Server - no ESX)
internal Certs
internal Sybase DB

Windows XP SP2 Registration - no Problem....

Who can me tell WHY ?
