Client printers fail to auto-create when users log on. An event is written to the Event Log with ID 1116 from source MetaFrame Events. The event contains Printer auto-creation failure. Reason: AddPrinter() failed with status 0x78A.

• This affects administrators and users.

• The user is unable to add a printer manually through the client network.

• Converting hex 78A into decimal 1930 and using net helpmsg provides the cause of the issue. Refer to the following output example:
  C:\Documents and Settings\Administrator.FTLRLAB>net helpmsg 1930

Note: The printer driver is not compatible with a policy enabled on your computer that blocks NT 4.0 drivers.

Complete one of the following steps to resolve the issue:

• If the preceding policy is set to Enabled, change it to Not configured.

  OR

  If the policy is set to Not configured, change it to Disabled.

• Run the following command from the command prompt:

  Gpupdate /force

Note: You must not experience this issue if the policy is set to Not configured. However, the policy might be behaving like it is Enabled. Citrix Technical Support might ask you to set the policy to Disabled. If the policy is not behaving as expected, contact Microsoft Support.
Note: Windows 2008 blocks the installation of NT 4.0 (version-2) drivers.

If this Solution do not resolve the issue, this policy might be set at the domain level.

Citrix recommends customers to not use kernel-mode (version-2) drivers unless absolutely necessary as they can potentially crash a server. Instead, user-mode (version-3) drivers must be used exclusively to prevent crashes and maintain server stability.

Problem Cause

A Windows Server policy named Disallow installation of printers using kernel-mode drivers causes this issue.
