SYMPTOMS
After you restore the SNA Server configuration (Com.cfg file) that includes Host Security Domains, the next time you go into the Host Account Manager (UDConfig), you do not see any of the Host Security Domains that were originally configured.



CAUSE
If SNA Server is removed and then reinstalled through the Setup process, some registry parameters for the SnaDatabase and SnaPMP keys are also inadvertently removed. These parameters are needed when using Host Security Integration.



RESOLUTION
To resolve this problem, obtain the latest service pack for SNA Server version 4.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

215838 How to Obtain the Latest SNA Server Version 4.0 Service Pack



STATUS
Microsoft has confirmed that this is a problem in SNA Server versions 4.0, 4.0 SP1, and 4.0 SP2. This problem was first corrected in SNA Server version 4.0 Service Pack 3.



MORE INFORMATION
The following steps outline when this problem can be observed:
 * 1) SNA Server is configured using Host Security Domains.
 * 2) The configuration (Com.cfg file) is saved.
 * 3) SNA Server is uninstalled, however, none of the Host Security Components are removed.
 * 4) SNA Server is reinstalled and the Com.cfg file restored.
 * 5) When you go into Host Account Manager (UDConfig), the Host Security Domains that were listed before the restore are gone.

When you view the application log of the Event Viewer, you see the following event messages:

Event 29:

PMP attempt to read registry values failed.

Event 531

Unable to Start SnaPMP Server.

Event 1214

Unable to access registry: This could be as a result of an unsuccessful attempt to de-install the host account cache, supplied code 0x0.
