Resolving Protocol Driver Errors for Citrix

By | 8 June 2017

When a client-user tries to hook up with a Citrix-published utility, typically they obtain the error message “Can Not Join To The Utility. Citrix Protocol Driver Error.”

There are lots of explanation why you may get this error. On this article, I clarify how one can examine and ultimately repair the issue by working by means of a sequence of steps.

The commonest motive for receiving this error is that the server has gone down.

Test all of the servers within the printed app. Are you able to ping all of the servers? If sure, are you able to RDP to all of the servers? If there’s a firewall between the consumer and the server, verify the firewall logs to see if any connections are being blocked.

If there’s a software program firewall working on the consumer or on the server, disable the software program firewall to see if this resolves the difficulty.

See in case you telnet from the consumer to every server on port 1494. If not, reboot the server. If that does not work, recreate the listener on the server.

The subsequent step is to verify within the eventvwr (occasion log viewer) on all of the servers within the printed app. Are you able to see any logs saying there is a matter with the Citrix license server, reminiscent of occasion ids 1004 or 1003? If sure, confer with Citrix article CTX564283 to troubleshoot these errors.

If “session reliability” (Widespread Gateway Protocol or CGP) is working, disable it and try to attach once more. If you happen to can join after disabling the session reliability, discover out what firewall port session reliability is utilizing from the Citrix console and ensure that firewall port is open between the consumer and the server. Once more you possibly can telnet to that port from the consumer to the server.

In case you are connecting through http (Net interface or http protocol inside an.ica file) attempt disabling any web proxy server you may need configured in your Web Explorer settings. Additionally, ensure that the “Routinely detect settings” will not be chosen, from IE > Instruments > Web Choices > Connections Tab > LAN settings > Routinely detect settings.

The issue could be a Home windows person profile challenge.

Go surfing to the consumer machine with a distinct person id and take a look at to hook up with the Citrix printed app. If you happen to can join, the difficulty have to be Home windows profile associated. If you happen to can not join there’s most certainly a problem with the consumer machine.

Replace the Citrix consumer model. Go to the Citrix downloads part and obtain and set up the newest Citrix receiver to your machine. In case you are utilizing an.ica file, open the file with notepad and search for the road that claims ProxyType=Auto and alter this to ProxyType=None.

Subsequent you possibly can attempt to reboot all servers within the Citrix printed utility.

It could even be a good suggestion to run Microsoft home windows updates to put in the newest service pack and hotfixes to your Microsoft working system. Additionally be sure to obtain and set up the newest Citrix hotfixes. (What’s a hotfix? In any other case referred to as a Fast Repair Engineering (QFE) replace, it’s a single, cumulative package deal containing a sequence of recordsdata, used to handle a selected downside in a software program product – these pesky software program bugs.)

Lastly, if nothing else has labored in your try to unravel your Citrix protocol driver error, set up the newest Microsoft service packs and hotfixes on the consumer. If that fails you possibly can attempt to reinstall Home windows and take a look at to hook up with the printed utility from a freshly put in working system.

Good luck!
