Windows Server 2003 R2 file sharing not working on external usb drive

Problem:

Filesharing is working fine except for on the External USB Hard Drive
which is attached to the server.

Description:

The system has two logical hard drives. One Mirrored set for the C:
drive, and one External USB drive as the K: (backup) drive.

Folders shared on the C: drive work fine, however shared folders on
the K: drive aren't working and cause a result such as:

"\\localhost\K$ is not accessible. You might not have permission to
use this network resource. Contact the administrator of this server
to find out if you have access permissions.

Not enough server storage is available to process this command."

The share \\localhost\C$ works fine and as expected.

There is 215 GB free on the C: drive and 47.2 GB free on the K:
drive. Permissions and security are similar if not the same for both
the Sharing and Security tabs on the C: and the K: drive. I can
access shared drives on the C: drive, and I can browse the K: drive
fine locally (and read and write to it).

There is an EventID 2011 in the System Event Log talking about
irpstacksize, however I've made the registry entry under \\HKLM
\CurrentControlSet\Services\lanmanserver\paramater s\IRPStackSize

Creating a new DWORD value, and have presently set it to 50 (hex 32)
(The maximum according to one Microsoft KB article I read).

I have rebooted and still can't access the drive.

I have scanned the External Hard drive for errors, and I have
defragged it.

I'm looking for a solution to this problem,

using Administrative shares should be done only for administrators.
The problem with external drives is often, that they are connected by the
system after the sharing process has been completed.
Does sharing work if you do it manually?
Delete any existing shares of that drive, then share again?
In this case you could try a script to start sharing delayed after server
boot.

If this is not the reason, there is still the server storage message you
mentioned.
Some threads in the Internet from another MVP (Hans Georg Michna) did show
the following solution working:

On the computer you are attempting to connect to, Set the IRPStackSize back
to the default (15), which seems to be altered for example by Symantec
Antivirus software. Perform the following steps:

1. Start regedit.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\lanmanserver\parameters.
3. Double-click IRPStackSize (or if this registry setting doesn't
exist, create it with type DWORD and ensure the case is correct).
4. Change the base to decimal, set the value to 15, and click OK.
5. Reboot the computer.
