PC Adm: Microsoft Mail Administrator Program and VDM

ID: Q157003

The information in this article applies to:

Microsoft Mail for PC Networks, versions 3.2 and 3.5

SUMMARY

Running the Microsoft Mail Administrator program under an MS-DOS virtual machine (VDM) is supported; however, just as with any application being run under a VDM, it is susceptible to causing corruption to the postoffice under certain situations.

MORE INFORMATION

Any networked MS-DOS application that relies on the sophisticated file I/O caching of a VDM could potentially experience file corruption because of one of the following:

Closing the VDM without properly closing down the MS-DOS application running in its window.
Ungracefully shutting the power down to a computer that has a running MS-DOS application under a VDM.
Faulty networking hardware or network card device drivers that do not properly handle I/O requests from the network and return improper values to the MS-DOS application.

When you run the Microsoft Mail Administrator program under a VDM in Microsoft Windows, Windows for Workgroups, Windows 95, or Windows NT, the following rules should be followed to prevent any corruption to the Microsoft Mail 3.x postoffice database files:

Always shut down the Administrator program by first pressing the ESCAPE (ESC) key, and then pressing Y, and then closing the VDM window.
If you are experiencing problems performing normal Administrator functions under a VDM, try performing the same task in a VDM on another workstation or from a native MS-DOS workstation.
If the problems persist, contact Microsoft Technical Support.
