The information in this article applies to:

Microsoft Windows 95
Microsoft Windows 95 OEM Service Release version 1

SYMPTOMS

On a computer running Microsoft Windows 95 (all releases) using the Microsoft TCP/IP protocol, the following error message may occur when certain data is received over the network:

This was called from 0028:<address> in VxD NDIS(01) + 00000D7C.

After this error message occurs, the computer may not receive further network data until Windows is restarted.
