Citrx XenApps - Unable to connect

Hi Experts,

I have citrix xenapp server 6.0 running on Windows server 2008 R2.

The citrix was working fine all day and I now notice that when I try to log into citrix from the we interface I am getting this error message:


" Cannot connect to the Citrix XenApp server. There is no Citrix XenApp server configured on the specified address."

The only thing that was changed today are:

I am in the process of migrating the DC which is a SBS 2003 box to server 2012 standard and exchange 2010 on a Windows server 2008 R2 box.

I changed the DNS entry on the citrix box to point to the new 2012 server (this is the main DNS server now). The citrix box was pointing to the SBS2003 before for DNS.

DNS is working find, I can ping and browse the 2012 server shares successfully.

Should I just re-boot the citrix box ?

Also, when I log into the console, can can see there are some active users that are logged in remotely.

Any thoughts ? Thanks

There is an entry for the citrix server in DNS.

I type telnet 1419 but this fails to connect.

telnet is working, I get IcA...

I noticed that when I ping the servers by name the new servers resolve to IPV4 address.

When I try the cirix server it respond with the IPV6 address.

Do you know what I am doing wrong ?  Thanks

Thanks for both of your help. The citrix receiver was the culprit.  un-installing/re-installing it resolved this issue.
