Hi,

I'm having problems connecting via citrix XenApp (what is odd is i have been using this connection for about a year now until it failed the other day)

To connect:
1. I log on to a VPN  ( VPN-1 SecureClient)
2. I click on the Citrix Xenapp custom connection I have made.
3. On Citrix dialog box -- it hangs on Connection Established... Negotiating capabilities

I have tried various suggestions from forums like allowing permissions on HKLM\SOFTWARE\Microsoft\MSLicensing
Deleting the HKLM\SOFTWARE\Microsoft\MSLicensing\store\License000x

No avail.

I tried creating a new custom connection as well -- but this time whenever I click on the dropdown menu for server list I get the "no server names returned".

I'm frustrated can somebody please help.

thanks!

There are a few things that could cause this so let's drill down on your issue.

First question:  Are you eventually able to launch the application even though it might saying "negotiating capabilities" for 10, 20+ minutes, or does it time out?

No it times out.

I have been trying to connect and without doing anything other the fixes i have mentioned yesterday
It has gotten worse. Now it hangs on "connection in progress"
then eventually saying " Cannot connect to the Citrix XenApp server"
The Citrix XenApp server is not available"


Background:
 I could connect to citrix without any issues before and my colleagues can also connect
but now it seems I am the only one who can't connect

I'm on Win7 but I have a virtual box ( SUN) installed and it runs on win XP ( I do this because the client VPN can apparently be installed on XP)
I connect to Client VPN ( CheckPoint VPN-1 Secure Client)
then connect to the Citrix Xenapp

I tried netstat I could see connection was established with the server I am trying to connect to with citrix when I was still encountering the the negotiating capabilities

Now --- I totally cannot connect

Oh, got it, I had it backwards...

So two things, first install the latest client.  Secondly, have you verified that it works without the virtual box?

Open a command prompt on the XP machine.

Telnet to the citrix server port 1494 and you should receive a response of ICAICAICAICA (see attached image)

I can't do it outside of the virtual box as the VPN Secureclient cannot be installed on win7
( I know its very frustrating --- the one we are provided only runs on XP -- i can't run it in Win7 even in compatibility mode)

We do not use citrix webplugin -- i might be wrong but the version 12 i can see is for webplugin.. is there a hostedapp version?

If so, i would appreciat if can send me the link

I'm not really a network person --- i just use citrix to connect to a clients machine.

I appreciate all the info

Yes, it's called "online plug in"  first link on the client download page at citrix.com

Also let me clarify my question about asking if it worked without the vbox.

Have you successfully installed the client such as a laptop running xp and the vpn client (no Virtual box)?

I haven't tried on a laptop running on XP

The thing is -- this citrix setup was working until last Sunday when it hung on negotiating capabilities.
and when I tried again this morning --- it could not establish a connection

Are you the administrator on this citrix server?  If not, it actually could be a server related issue.

I'm not sure really.
I guess I have to ask the clients network people

Yes, especially if it was working and now it's not...  This issue is one you certainly want to address with your client.  Good Luck and let me know how it goes.

Thanks dnsguru

apprently, i was presented with a solution from a colleague. He did not use citrix at all but just installed a different VPN and just jump from a certain machine to another.

point is yours! thanks for your patience

Also... if you think it might be local to your machine and you have access to a pc on the internal lan, you could rdp to that pc, launch a browser and see if you can connet to citrix server.

What fixed it for a non-local admin user was to grant full permissions on the registry key: MSLicensing.
