I tried the following command on a newly imaged PC,

zac reg -g http://a2zcm1.nara.xxx

Processing Command : reg

user name : xxxxxxxx
password: xxxxxxxx

Unable to register with the server at https://a2zcm1.nara.xxx
Service Error. code: -28, message: InternalDataModel exception while trying
to create/update device: NARA-DESKT03
com.novell.zenworks.datamodel.exceptions.InternalD ataModelException:
com.novell.zenworks.datamodel.exceptions.DataModel UsageExceptions : You are not
logged in

Any ideas why I might be getting this error?
