SYMPTOMS
LUs or pools that are assigned to a Workstation record that is deleted in a Microsoft Host Integration Server configuration may also be removed from other Workstation records. This behavior only occurs when the same LUs or pools are assigned to multiple Workstation records in a Host Integration Server configuration.



CAUSE
When you delete a Workstation record that has LU or pool assignments, the links to the LU or pool record must be removed from the Workstation record. The Host Integration Server configuration DLL (Snacfg.dll) deletes the LU and pool records without verifying the associated Workstation record. Therefore, the LU or pool records will be removed from the deleted Workstation record and from any other Workstation records that they are assigned to.

WORKAROUND
You can use one of the following methods to prevent LU or pool records from being deleted from other Workstation records:  Delete the LUs or pools from the Workstation record before you delete the Workstation record. SNA Manager will not let LUs be deleted from the Workstation record if the LUs are being used. Use the SNA command-line configuration utility (Snacfg.exe) to remove the LUs or pools from the Workstation record before you delete the Workstation definition. Snacfg.exe will let you remove LUs that are being used from a Workstation record. Use the following format to remove LUs or pools from a Workstation record by using Snacfg.exe:

snacfg workstation  /remove:





STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was corrected in Microsoft Host Integration Server 2000 Service Pack 2.



MORE INFORMATION
The following sample configuration can cause the problem that is described in the &quot;Symptoms&quot; section:
 * 1) Create two Workstation records in the Host Integration Server configuration by using SNA Manager. For example, name the records Workstation 1 and Workstation2.
 * 2) Assign the same LUs or pools to each Workstation definition. For example, LU1, LU2, and LU3.
 * 3) Save the Host Integration Server configuration.
 * 4) Delete the first Workstation record that you created. For example, delete Workstation1.
 * 5) Save the configuration.
 * 6) Refresh the configuration or restart SNA Manager.

Notice that the LUs or pools have also been removed from the second Workstation record. For example, this record may be Workstation2.

The problem does not occur if you delete the second or any subsequent Workstation records. This problem only occurs when the first Workstation record to which the duplicate LU or pool records were assigned is deleted from the Host Integration Server configuration.
