VB.NET UDP Clinet On Windows Terminal Service Session

Hi Friends

i am Using VB.NET 2005 Application as UDP CLIENT on Windows Terminal Services, on first session i am able to run my application, but on all others i am getting error message “Only one usage of each socket address (protocol/network address/port) is normally permitted”.

the same application i am using with IP*Works UDP Control that allow me to share same UDP port but thats in VB6. now i am in middle of migeration to VB6 to VB.NET

So guys need your suggestions or help in this regards.
