Ax 2009 disk full error Cannot create temporary file: C:\Program Files (x86)\Microsoft Dynamics AX\50\Client\appl\standard\tmp\$tmp001303e8.$.


Ax 2009 disk full error

Hi Friends

This problem only seems to occur on 64-bit operating systems and it can be very tricky to pin down the cause....
It occurs on both Terminal servers and Citrix Servers seemingly at random, we've noticed that the most consistent way to reproduce it (for this implementation at least) is by trying to generate a Customer Account Statement, but it can occur also occur when using Select Criteria, trying to generate a report, or when trying to view the permissions tree in a user group

The problem






Cannot create temporary file: C:\Program Files (x86)\Microsoft Dynamics AX\50\Client\appl\standard\tmp\$tmp001303e8.$.
The disk may be full.

Which is strange since the disk isn't full on the AOS server or the Citrix/Terminal server
There is a workaround which is to run the Ax client as an Administrator but that can be a major security flaw and isn't a long term solution

The Cause
There's a registry setting which tries to create a temporary sub-directory each time a user connects to a Terminal/Citrix server.
The problem is that when this temporary sub-directory gets created, it doesn't appear that the Ax client has access to it
So while the user may have the correct access to the %temp% directory within their Citrix/Terminal server user profile, they don't have access to the %temp%\1 or %temp%\27 or %temp%\942 sub-directory (the exact number varies and is rarely the same)

The Solution
The solution is to set the registry on the terminal server to not create these sub-directories within the temp folder and just to use the main %temp% directory instead
How do you do that? Well I'm glad you asked, all it takes is a little registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server]
"PerSessionTempDir"=dword:00000000

This change needs to be made in the registry on all the Citrix/Terminal servers that are used to connect to Ax

Here's a handy KB article with a bit more information about these keys

Couldn't find this solution posted anywhere else on the internet so it looks like this is a first. Hurrah!


Enjoy Friends...

  1. I was getting this on 2012 R2 and R3 as well. We were also receiving "unable to save template.ico" warning messages. This appears to have resolved both of those issues. Thank you.
