SYMPTOMS
When you attempt to shut down Windows, your computer may stop responding (hang).



CAUSE
This behavior can occur if you are using Cisco TCP/IP Suite 100 as your Transmission Control Protocol/Internet Protocol (TCP/IP) stack. The Windows 98 shutdown process waits for a return from the NdisCloseAdapter variable call to the networking stack. The Cisco software does not recognize this call, so the computer appears to not respond.



RESOLUTION
To resolve this behavior, remove Cisco TCP/IP Suite 100, and then install Microsoft TCP/IP. To do so, follow these steps:


 * 1) Click Start, point to Settings, click Control Panel, and then double-click Network.
 * 2) In the list of installed network components, click Cisco TCP/IP Suite 100, and then click Remove.
 * 3) Click Add, click Protocol, and then click Add.
 * 4) In the Manufacturers box, click Microsoft, and then click TCP/IP in the Network Protocols box.
 * 5) Click OK, and then restart your computer when you are prompted to do so.

To work around this behavior, Cisco Systems suggests reverting to the version of the Vnbt.386 file included with Microsoft Windows 95. To do so, follow these steps:

 Click Start, point to Find, and then click Files Or Folders. In the Named box, type vnbt.386, and then click Find Now. In the list of found files, right-click the Vnbt.386 file, click Rename, and then type a new name for the file (such as Vnbt.xxx). Close the Find window. Extract a new copy of the Vnbt.386 file from your original Windows 95 disks or CD-ROM into the Windows\System folder. The Vnbt.386 file is located in the following locations:

 The Win95_12.cab cabinet file on the Windows 95 CD-ROM.</li> The Win95_18.cab cabinet file on the Windows 95 OEM Service Release 2 (OSR2) CD-ROM.</li> The Win95_13.cab cabinet file on disk 13 of the original Windows 95 DMF floppy disks.</li> The Win95_20.cab cabinet file on disk 20 of the original Windows 95 non-DMF floppy disks.</li></ul>
