This basically is an error that the network driver is giving SRV on the send IRPs. It usually indicates a send is issued on a connection which is no longer in a state valid for sending. For example, send when a connection has not reached connected state will return STATUS_INVALID_DEVICE_STATE. If disconnect has been initiated, then the same error would be returned for further sends.
1. Antivirus Filter driver interfering with the network stack
2. An outdated or bad network card driver
3. A bad NIC
4. Network Teaming software
5. WAN Optimization devices
6. Mismatched Speed and Duplex settings between the NIC and switch
7. A spotty connection to a switch port
- Make sure that the firmware for the network switches/WAN accelerators and routers are up-to-date.
- Update the NIC firmware and driver.
- Update the NIC teaming software/driver.
- Update the Antivirus software or completely uninstall (for relief, and follow-up w/ the AV vendor)
- Manually set the speed/duplex
- Replace the network cable(s)
- Try a different switch port
- For the WAN optimizers, to try getting the packets from being modified, try using encapsulating the packets using IPsec.
