Users who currently operate either a Windows
95 or NT 4 based Networking System, may experience data corruption and system
hang-ups when operating MS-DOS based applications over the Network. This problem
exists on both dedicated File Server and Peer-to Peer configurations.
Considerable corruption can occur spontaneously without warning and can render
valuable data unusable without expert software engineering attention.
You can download the new versions from this
page by clicking on the following file vrdrupd.exe
The file is 215,728 bytes in length. When run
it starts up a standard setup to install the new vredir.vxd
(156,773 bytes, dated 11-Sep-97 11:16 am) and the new vnetsup.vxd (17,595 bytes,
dated 30-May-97 11:12 am).
(Note: to find out the version of your
VREDIR.VXD file you can do the following. Start up Explorer, find the file in
\WINDOWS\SYSTEM and right click on it. Select Properties and then click on the
Version tab. The version of the file is the top item.) You'll have to reboot
your Windows 95 system to complete the installation.
Solution Part II
The next step is to add a new registry entry to the Windows 95 system, using Windows 95's REGEDIT.EXE.
Walk down the key tree until you reach the
VREDIR subkey. Right click on the right hand pane, select New then Binary value.
Enter the identifier DiscardCacheOnOpen and press Enter. Double click on the new
identifier and a dialog is shown where you can enter the data 01.
Once you've exited REGEDIT, you will need to
reboot your machine for the new setting to take effect. Only the new VREDIR.VXD
will understand this setting, previous ones will ignore it.
Solution Part III
If you are using a Windows NT 4 server as
your file manager (in other words, the shared data files reside on a Windows NT
4 server machine), there's one more step to take: You need to turn off
optimistic locking at the server. You need to add a new registry key on the
Windows NT 4 Server (or modify the current one if it exists).
