Citrix Server Not Available?

[LLudlow]

Sometimes for no reason users trying to connect to the citrix server are getting this message: Citrix Server is Not available. Please try again later.

If they try again a couple of times they are able to connect. This is a new problem, and has never happened before.

Stumped

I am also encountering this problem. It may be related to the # of TS licenses on your network. I am still researching.

How many users are connecting to the server...?? How many active connections are there on the server when the fault occurs...??? Are all the connections from a LAN....??? Can you still connect to Citrix Admin on the server when the fault happens...???

Sorry for the questions.........!!!

There are at any time up to 25 users connecting to the server. But i do have 25 licenses so that should not be the problem. The connections are all over a LAN. I can still connect to Citrix Admin when this does happen. When the fault happens there is often only one or two active connections.

How are you connecting to the Server on your LAN... Solely through IP I assume...

I had a workstation doing much the same thing until I discovered that someone had modified the Network Properties and put values in for DNS and WINS that, although weren't 'incorrect' did seem to be causing the problem.

One thing I noticed is that when I couldn't connect to Citrix, if I opened a DOS Prompt and tried to PING the server, I couldn't. If I waited a minute or so (or did a release/renew on the NIC) I could then PING the server successfully again and make a connection to the Citrix Server with no problems...

MISAdmin,

I have static Ip addresses assigned to the client computers, so there should be no problem with that. Also I am getting the same problem on my own client computer which no one has been on. The weird thing is that sometimes i cannot get connected but if i wait for say 30 min then I can get connected. It seems as if there is no reasoning for it.

Sounds like a network fault then....??? R all the "problem" machines connected to a particular segment on the LAN..?? Only other area to check would be the network connection on the server...?? If possible try moving to another switch/hub port...?? U could also look at the network stats for the server...Programs/Admin Tools/Windows Diagnostics/Network....Look at the Statistics for Network Errors, Failed Sessions, Server Disconnects and Sessions Timed/Errored Out....normally these counters will be zero or low....

This was a common occurence on our site. Stopping/Starting the ICA Browser Service and Terminal Server Licencing cures the problem. We have scheduled this to run every night on all servers. It cures the problem but obviously isn't the fix for it...
