Windows 2008 server THE CLIENT COULD NOT ACCESS THE REMOTE A

I have install 2x in windows 2008 server.
I have a problem
"THE CLIENT COULD NOT ACCESS THE REMOTE APPLICATION"
"THE MACHINE MIGHT BE TOO BUSY TO ACCEPT NEW CONNECTIONS OR NETWORK PROBLEMS ARE PREVENTING YOUR CONNECTION"
"PLEASE TRY CONNECTING AGAIN LATER"



Thank you.

 

SOLUTION

I SPEAK ENGLISH BAD, I AM SORRY
I HAVE FIND ONE SOLUTION, I HAVE CHANGE THE CONECTION PORT , THE PROGRAM IS 80, I ATTACH 81 (CLIENT AND SERVER)

THANK YOU
