Hi there,
We are using MS Windows server 2003 R2 enterprise SP2 at our site over a decade. However, recently we encountered that one of the application services stopped working suddenly for reasons unknown.
When checked on the windows event logs, an error shown that “error binding listening socket to port (error 10048):Only one usage of each socket address (protocol/network address/port) is normally permitted”.
As per Microsoft support (Winsock error message when you use a program that tries to bind to TCP network ports on a Windows-based computer: "WSAEADDRINUSE (10048)"), it stated that the cause of the issueoccurring is due to the “Application Layer Gateway service” reserves the TCP ports in the 5001 to 5032 range by design. However, none of the application using this range as per our port configuration.
The default startup type is Manual and started. So, this ALG service is currently running. But in order to avoid such behavior in future it was recommended to stop/ disable the service as per MS Windows support.
Kindly advise if stopping this service will have any impact on theexisting applications running on the server.
