I have a file and print server that has become inundated with the following
Srv warnings, event 2021, with the # being filled in with a variety of
different numbers. How do I get to the bottom of this? every article i've
come up with says it could really be anything causing this with not much help.

The server was unable to allocate a work item # times in the last 60 seconds.
 
Thanks for the article. I don't have either of the keys MaxWorkItems or
SizReqBuf in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters

I only have 1GB memory in the server, should I go with adding the values of
8192 and 16644 to see if that lessens the 2021 events then?

is there a way to make it log any details about the work item that it
couldn't process, or a way to take a snapshot of the queue in order to see
what's filling it up?

Thanks Dave. I checked out the article about 2021, and that registry key
mentioned, mine is set to 0, where the article suggests 1000. Would
switching this to 1000 have any negative affect on anything? since this
server is my file & print, it's a big deal when i take it down or if it goes
haywire.

Have not tried tweaking that setting yet. In reading more about it, leaving
it at 0 allows Windows to adjust it dynamically. I'm debating whether I
should change it or try installing more RAM in the server.

You could open a ticket with Microsoft, but here is usually the recommended
actions if you indeed have the 2021 and 2022 events :


1) Set the following registry key to the new value 15 in HEX:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

IRPStackSize:Reg_Dword:0x15



2) Reduce Event ID 2021 errors


To specifically address Event ID 2021, start Registry Editor and locate the
following registry subkey:



HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters



Then, add or modify the following DWORD registry values:


Description: Maximum Work Items
Value Name: MaxWorkItems
Data Type: REG_DWORD
Value data: 0x2000 or 8192 (decimal)

Description: Size of a Requested Buffer
Value Name: SizReqBuf
Data Type: REG_DWORD
Value data: 0x4104 or 16644 (decimal)

3) Reduce Event ID 2022 errors


To specifically address Event ID 2022, start Registry Editor, and move to
the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters


Then add or modify the following DWORD registry values:
Description: Maximum Free Connections
Value Name: MaxFreeConnections
Data Type: REG_DWORD
Value data: 0x1000 or 4096 (decimal)

Description: Minimum Free Connections
Value Name: MinFreeConnections
Data Type: REG_DWORD
Value data: 0x100 or 256 (decimal)
