Novell ZENworks 7 Desktop Management Support Pack 1 - ZDM7 SP1 Desktop Management
During Login to the Middle-Tier server, an initial login login request to the Middle-Tier server is seen in the trace, but the packet was very small and the login failed.
After a 15 second delay, another much larger packet was sent automatically that then successfully authenticated to the server.
The issue described above is not seen in most environments, but Novell was able to resolve the matter by adding either of these two settings to the client machine.
HKLM\Software\Novell\LgnXTier,DisablePassiveModeLogin (DWORD: Value of 1)
HKLM\Software\Novell\LgnXTier,PassiveModeLoginRetryInterval (DWORD: Value of 1)
The first setting disables the passive login which was failing.
The second changes the default retry from 15 seconds to 1.
