The registry value IRPstackSize, which may be listed at HKEY_LOCAL_MACHINE\<br>
SYSTEM\ CurrentControlSet\ Services\ LanmanServer\ Parameters defaults to 0x4 if<br>
the value is not explicitly present. Valid values range from 0x1 to 0xC (1 to<br>
12). Depending on the hardware configuration of a specific machine, the default<br>
value may not be large enough for the Srv service to properly administer shared<br>
directories on some of the physical drives. You may see one or both of the<br>
following event messages:<br>
<br>
Event ID: 2011 Source: Srv<br>
The server's configuration parameter "irpstacksize" is too small for<br>
the server to use a local device. Please increase the value of this<br>
parameter.<br>
<br>
Event ID: 0<br>
Source SRV<br>
Description: Description for Event ID 0 could not be found. It<br>
contains the insertion string \device\LanManServer<br>
<br>
You may receive one of the above error message when a Windows NT client tries to<br>
access certain shared directories on such a server.<br>
<br>
When a Windows for Workgroups client tries to access the same shared directories,<br>
the following message will be generated:<br>
<br>
Path not found.<br>
<br>
To increase the value of the parameter when it is not already present, go to the<br>
key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<br>
LanmanServer\Parameters. The value of IRPStackSize defaults to 0x4 if it is not<br>
explicitly present. If the key is not present, choose Add Value in the Registry<br>
Editor. The Value Name should be IRPStackSize and the Data Type is REG_DWORD..<br>
<br>
If you are encountering this error message, try gradually increasing the value of<br>
IrpStackSize in order to find the minimal value which resolves the problem.<br>
Using a value that is larger than necessary can result in an unnecessary waste<br>
of system resources. Other factors can also lead to this error message. If<br>
problems persist with all legal values for IrpStackSize, restore IrpStackSize to<br>
its original value and another explanation for the error must be sought.<br>
