Hi Aram,
Just check whether your able to see the dw_ & ms_ process on os level.
also run the dpmon pf=<instance profile> to check the work process and are running correctly.
IF there is no work process running then do check the logs under /usr/sap/SID/DV*/work for dev_w0 and dev_ms log file for more on the error.
Also based on your instance number the port for ms will change and do check the 32<Instance number port> for listening.
And do verify your sap gui entries are correct to connect using SPAGUI.
And do maintain the sapms<SID> entries in your C:\Windows\system32\drivers\service directory
Let us know if you need any further help.
Regards,
Ram
