If you have ever used any Unix/Linux based systems you know that windows does not even come close to providing as reliable service management as its counterparts. I have been burnt by the stuck services issue so many times that it was natural for me to look for alternate mechanisms.
VB script is a scripting language developed by Microsoft and is a limited variation of Visual Basic programming language. To me its a much better and more powerful alternative to Batch Scripting.
Being new to VBScript i had to spend some time initially to grasp the basics but when i did it was quite easy. Here is a simple VBscript to manage windows services. You just need to modify the number of services to manage and their names and the script lets you bulk start/stop, check status and individually control each service. Thankfully since i have used this script i have not experienced the stuck services issue and i am strongly inclined to believe that most services start/stop issues may be caused by bugs in the GUI based Windows Services Manager (this is just speculation and i have no conclusive evidence to prove it).
Execute the following from your command prompt to run this script:
cscript [path to script]
The script:

dim strComputer

s_quit()

' Modify this array size to add or remove services. The length of this array should be
' exactly same as the number of services.
' Note: If you want to initialize this array to hold 4 services, set its size to 3. The array
' like most has a zero based index i.e. 0 to 3.
dim myservices(3)
' specify the actual service names here
myservices(0)="<service-mgmt1>"

Hope this script helps you alleviate some of your windows services woes.
Disclaimer: I am not a VBScript developer. If you find any bad coding practices please do let me know and i will be more than happy to fix my script. Also the exception handling could be done in a much better fashion.
