Xenapp on Xenserver: first xenapp server can not contact licesing server

I created 2 vm's on my new xenserver.
xen runs licensing server and Web interface

xen1 is the first of many xenapp servers

I disabled teh firewalls on both. I am able to ping from one to the other.

I can open the wi on both.
The licensing server fails to connect.  I have no idea where to begin trouble shooting this.
I can open the LMC on both servers.

And a RPC error comes up from xen1 to xen trying to view webinterface via AMC. (related?)

I did a netstat -a to see what was running.. i read port 27000 is the lic server port.
The only listing of this port has a local address of
i dont used netstat alot. maybe thats normal.  Not sure why it be set to the loopback address?
no idea how to change it

FYI Web Interface 5.1 and up now no longer stores any Web Interface information in the Citrix Datastore (in 4.x versions you used to have the option to have it stored in datastore so it could be administered from any server) - so essentially Web Interface administration can now only happen on the Web Interface server's locally installed AMC only...

Just something to keep in mind.

The licensing server may have resolved itself.. for now.  The only way i know to test it is to reboot.  the error dint come up.  I still get the rpc error
tring to view WI via xen1's AMC.  I cant get it to work.  It works from xen, which is odd... but keeps it from being a critical issue, more of a annoyance.
Did you make sure your account was able able to do remote com+? Make sure you have enable network com+ in add and remove windows components as well as making sure the account is in the Distributed COM Users group on each server.

Its windows 2008. there is no add remove components. there are roles and features. neither have it?

Sorry got distracted did not finish that comment.

Where do i go to check if that is done?
I would think citrix setup would have confirmed it was installed?

Ah 2008 - sorry wasn't listed so I assumed 2003.


To enable network DTC access and configure Windows Firewall on Windows Vista or Windows Server 2008
Click Start, click Run, type dcomcnfg and then click OK to open Component Services.

In the console tree, click to expand Component Services, click to expand Computers, click to expand My Computer, click to expand Distributed Transaction Coordinator and then click Local DTC.

Right click Local DTC and click Properties to display the Local DTC Properties dialog box.

Click the Security tab.

Set the following options on the Security tab of the Local DTC Properties dialog box and click OK.

That did not fix it.
EricIT ManagerAuthor Commented:
Could be coincidence. but now my mfcom is broken since following this :(
it wont start.  now i cant discover anything via the AMC
Have you tried doing a repair of the XenApp Install? that should recreate all the services, credentials, etc.
EricIT ManagerAuthor Commented:
i did this and it fixed it.  
it still cant view the other servers web interface.  i find that odd. this was never a issue with PS 4.5 on 2003 server.
EricIT ManagerAuthor Commented:
hmm  additional note:
xen (web inteface /licensing server) can view web inteface in the AMC. it CANNOT discover Xen1 (only xenapp server so far)
Xen1 can discover itself in AMC but not the web inteface on Xen.
they both can ping eachother.
EricIT ManagerAuthor Commented:
and explains why it dont work.  that seems dumb to me. but i guess its the answer i been looking for.
