Try to delete the auto created printer and check. Also if possible update Receiver for Windows 3.4 you can download the client http://support.citrix.com/article/CTX133997
Are the Citrix servers patched to the latest level, including any rollups?
Are there are any event log entries at the time of the crash?
What versions are in use?
Is it consistent across all users or specific ones? What are they doing at the time?

Hi,
Citrix rollup pack PSE450W2K3R07 has been installed
Nothing specific entry related to this error
Citrix version-Citrix xenapp 6.0
Error is for all users.as there are multiple users not sure what they exactly doing at the same time

But that HF is for XenApp 5.0 downwards yet you say you're running XenApp 6.0
At the first stage, I would update to ensure you have the relevant, and up to date, XA 6.0 Hotfixes on.

As Tony1044 said, you need to ensure you have the latest relevant hotfixes for XenApp 6.0.
If you did this and yet you still face the HDX crashing issue, then try disabling the client side HDX flash to see how it goes, as follows:
In the following registry key from the client side
HKCU\Software\Citrix\HdxMe
disable UserEnabledFlash by changing its value to 0.
If this resolves your issue, then you need to know that the client side Flash is conflicting with the server side Flash and causing the issue. However, this should be considered as a temporary work around. I would suggest to test with the latest Citrix plugin to see whether this would resolve the Flash conflict issue.

Did you also check with a user account with admin privileges on the server? So any permission related issues can be vetted out.

Hi,
Finally I figured it out.There were two issues
1)Patches were not upto date
2)After installing latest patches the problem reappeared once but deleting wdica values in registry fixed the issue as beow:
1. Run Regedit.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\
3. Create a key named WDICA.
4. Manually add the following values:
ErrorControl: REG_DWORD : 0
Start: REG_DWORD : 0x3
Type: REG_DWORD : 0x1
5. Reboot the server.
6. After the reboot, a subkey named Enum will be created with the following values.
0 : REG_SZ : Root\LEGACY_WDICA\0000
Count : REG_DWORD : 0x1
NextInstance : REG_DWORD : 0x1
7. Make a Custom ICA Connection to the server’s IP address. It should connect successfully.
If the above steps do not resolve the issue, check for the existence of HKEY_LOCAL_MACHINE\SYSTEM\
If the key does not automatically regenerate itself, you can restore a copy of this key from a known good server or manually create the entries. When replacing this key with a copy of the key from another server it is necessary to navigate to the following location:
HKEY_LOCAL_MACHINE\SYSTEM\
Delete the data of the following value located within the above referenced key and then reboot the server:
"DeviceReference"=dword:81
Upon reboot the data should repopulate.

Personally I feel that the OP pointed out that the resolution came in two parts: update to latest hotfixes and implement a registry key change;
Mutawadi agreed with me in his post that the latest hotfixes should be put on and did point out a registry key but it wasn't the one in the final fix.
Either the question should be closed and refunded or I should get points for pointing the OP in the right direction.

Unless the author comes back with his comments and reasons, I recommend that:
