SYMPTOMS
SNA Server clients are unable to get application sessions on SNA Servers configured through the OtherServers registry parameter when the Firewall registry entry is also configured on the client. The OtherServers registry entry is ignored if the Firewall entry is present.



CAUSE
The OtherServers and Firewall registry entries are designed to be mutually exclusive.



RESOLUTION
An update is available that allows the Firewall parameter to be ignored when the client is trying to connect to a SNA Server defined in the OtherServers parameter.

SNA Server 3.0

MORE INFORMATION
In addition to the hotfix, a registry parameter has to be added to allow the Firewall parameter to be ignored. To add the registry value, perform the following steps:

SNA Server Client for Windows NT
 Start Registry Editor (Regedt32.exe), and go to the following location:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services \SnaBase\Parameters\SnaTcp\

NOTE: The above registry key is one path; it has been wrapped for readability.

  Add the following information:   Value Name: UseFireWallWithOtherServers Data Type: REG_SZ String: NO NOTE: The default string value is YES, which is also the default if the entry does not exist. 

SNA Server Client for Windows 95
 Start Registry Editor (Regedt32.exe), and go to the following location:

HKEY_LOCAL_MACHINE\Software\Microsoft\SnaBase\Parameters\SnaTcp\

</li>  Add the following information: <pre class="fixed_text">  Value Name: UseFireWallWithOtherServers Data Type: REG_SZ String: NO NOTE: The default string value is YES, which is also the default if the entry does not exist. </li></ol>
