for a hotfix applicable to Microsoft Windows 2000.
From a newsgroup post: "I was repeatedly getting an event 2006 source Srv that the "server received an incorrectly formatted request from" a particular Win 98 workstation. A friend told me that Win 98's driver for the Realtek chipset used by many cheap nics is broken. If your nic uses an 8019 or 8029 chip, you will get these errors sporadically. You need to download a new driver. The drivers for Win 95, Win NT4, and Win 2k work fine, it is just the Win 98 driver that has problems".
According to a Usenet post: "Typically, an application error causes this event to appear in your event log. An application that utilizes LockingAndX and AndX may have been the course. Other possible causes are a corrupted NIC driver or faulty network card or that the srv.sys is out of date or corrupt. You might want to reapply the latest service pack. If the event viewer indicates a consistent pattern, you can reduce the frequency of these errors by setting the autodisconnect time to slightly higher than the time between the errors. From a command prompt, type in the following:
"net config server /autodisconnect:30"
Most likely cause is the NIC in the client machine and a application error.
If the backup server is participating in a Backup Exec Network Storage Executive group this issue can occur if the Backup Exec for Windows NT Agent Accelerator (NTAA)server in not installed on the server mentioned in the error. See Veritas TechNote 231195.
