Citrix


A server solution that uses Microsoft Terminal Services software to deliverWindows applications to PCs, Apple Macintosh computers, X terminals and UNIX workstations. This enables users of those systems to access and use those programs which are available to those using the Windows operating system. Citrix servers use two technologies; WinFrame and Independent Computing Architecture (ICA).

Citrix was founded in Richardson, Texas in 1989 by former IBM developer Ed Iacobucci, with $3 million in funding Following its initial setup and development, Iacobucci moved the company to his former home of Coral Springs, Florida.
Citrix was originally named Citrus but changed its name after an existing company claimed trademark rights. The Citrix name is a portmanteau of Citrus and UNIX
How to disable print drivers from automatically updating the DataStore?
When a new printer or printer driver was installed on a MetaFrame server, a substantial amount of traffic (in the order of 8 to 10MB per second) occurred between the IMA Service and the data store the IMA Service was using. This occurred because the IMA Service needed to update the Management Console for MetaFrame XP with the information about the new printer or printer driver, which caused the huge amount of network traffic.
To resolve this problem, navigate to the following registry key and change the value of fDisablePrinterWorkerThread to 1:
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMAPrinter
Type: REG_DWORD
Value: fDisablePrinterWorkerThread = 1
After making this change to the registry, restart the IMA Service for the change to take effect.
When the registry switch is set to 1, the IMA Service does not automatically update printer or printer driver information to the Management Console. You need to update this information manually. To do this, click Printer Management in the left panel of the Management Console and then double-click Update Printer and Driver.
