I'll post the one I created so you can get some ideas from it. It's very simple.

SERVER

;Server Script. RUN FIRST
TCPStartUp()
$MainSocket = TCPListen(TCPNameToIP(@computername), 65432,  100 )
If $MainSocket = -1 Then Exit
While 1
    $ConnectedSocket = TCPAccept( $MainSocket)
    If $ConnectedSocket >= 0 Then
        msgbox(0,"","connected",1)
        ExitLoop
    EndIf
Wend
While 1
    $Message=TCPRecv($ConnectedSocket,2048)
    Sleep(25)
    If $Message<>"" Then
        Switch $Message
            Case "IPAddress"
                $Info=@IPAddress1
            Case "ComputerName"
                $Info=@ComputerName
            Case "UserName"
                $Info=@UserName

Run the server at the server computer. Change the IP address to the server's ip in the client script and then run it. You can send commands like: ipaddress, username, etc. The script will tell you that info from the server comp.

I'm sorry I can't really help you but I'm using someone else's computer.

Well just from looking at it I can find many weird things. Like:

Select
    Case Run($exe2)
    EndSelect

Run($exe2) will always be called. And what is $exe2??

I'm not familiar with the TCPFuncs.au3 include. Have you even tried mine? Just modify it and it'll do what you want.

Why close the connection every time?

I made some modifications to yours (well, pretty much everything. And now you can run programs at the server and send messages too)

SERVER

TCPStartUp()
$MainSocket = TCPListen(TCPNameToIP(@computername), 7000,  100 )
If $MainSocket = -1 Then Exit
While 1
    $ConnectedSocket = TCPAccept( $MainSocket)
    If $ConnectedSocket >= 0 Then
        msgbox(0,"","connected",1)
        ExitLoop
    EndIf
Wend
While 1
    $Message=TCPRecv($ConnectedSocket,2048)
    Sleep(25)
    If $Message<>"" Then
                If StringInStr($Message,"/run") Then
                    $exe2=StringSplit($Message,"/run",1)
                    MsgBox(0,"",$exe2[$exe2[0]])
                    Run($exe2[$exe2[0]])
                    ContinueLoop
                EndIf
                If StringInStr($Message,"/msg") Then 
                    $msg=StringSplit($Message,"/msg",1)
                    MsgBox(0,"Message",$msg[$msg[0]])
                EndIf
    EndIf
WEnd
