SYMPTOMS

A "Stop 0x0000001E - KMODE_EXCEPTION_NOT_HANDLED" error message may occur when the SNA Server service starts after you install the Digi Datafire 570 SDLC link service. The Stop screen information indicates that the Digi570mp.sys driver is the cause of the problem.

CAUSE

This stop error can occur if the Digi Datafire 570 SDLC Link Service has been installed by using the External Link Service (Linkset.exe) on the Tools menu in the SNA Server Manager instead of using the Insert Link Service option.

RESOLUTION

To resolve this problem, you must completely remove the link service and driver files, and then reinstall them. To do this, perform the following steps.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
  1. Remove the Digi Network adapter by double-clicking the Network icon in Control Panel, and then selecting Adapters. Restart the computer when you are prompted.
  2. Remove the External Link Service drivers by selecting the Digi/Sync Link Service. To do this, on the SNA Server Tools menu, click External Link Services, select Links, and then click Remove.
  3. Remove the files associated with the Digi Link Service from the from the SNAROOT\System\Hwsetup directory. The files all begin with DIGI.
  4. In Registry Editor, remove all of the references to the Digi drivers. These drivers are located under the following registry keys and all begin with Digi, Dgi, or DGP:

    HKEY_LOCAL_MACHINE/Software/Microsoft
    HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services

  5. Reinstall the Digi Surefire adapter through the Control Panel Network icon by selecting Adapters, and then clicking Add.
  6. Configure SNA Server to be the layer 2 protocol for that adapter. To do this, open the properties for the adapter, select the line to configure, and then select SNA as the protocol.
  7. To install the link service, open the SNA Server Manager, choose Insert, select Link Service, select Digi SDLC, and then answer the remaining configuration questions as appropriate.

MORE INFORMATION

A Stop error message can also occur if the incorrect Digi Link Service for the adapter has been installed or is misconfigured.
