We have noticed that when we run sc.exe to remotely stop or start a service from some servers it responds with in 3 seconds but when we stop or start the same service on the same remote server from different servers then it takes 25 seconds for the program to respond. I tried this from my Windows 7 PC and it runs slow. I've also tried running this from two Windows 2003 servers and it runs fast. I've also tried this from a few windows 2008 servers and on two of them it works slow and on one of them it runs fast. Is there some way to configure the sc.exe to run fast or there some setting in the OS that need to be tweaked?
