Increase IRP stack size

When you access shares on a computer running Windows NT Server from a Windows NT client and the IRPstackSize parameter is set too low on the server, you may receive the error message. In the server event log, you will probably see either:

Event ID: 2011
Source: Srv
The server's configuration parameter "irpstacksize" is too small for the server to use a local device. Please increase the value of this parameter.

Event ID: 0
Source SRV
Description: Description for Event ID 0 could not be found. It contains the insertion string \device\LanManServer

To resolve, increase IRP stack size:
Key: SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Name: IRPStackSize
Value: 0x4default, range=0x1-0xC

An error message on the server, on the other hand, stating that there is not enough disk space to run a service when there is plenty of DASD is caused by having mixed network components from the original install and an update. Easyily fixed by reapplying the lastest service pack you are using.
