I'm not sure if this will help, because the RPCSS.exe process is a necessary part of of the system which allows other parts of the OS to talk to each other. There's more information about this process in the link below;
But what you can try is to load XP into Safe Mode, which is XP's troubleshooting mode. it only loads the bare necessary processes and services, so you may be able to start XP this way. Start the computer and after the BIOS POST messages, (the BIOS displays messages about the system hardware), but before windows begins to load, start tapping the F8 key once a second. If you time it right, you will see a list of Safe Mode options with "Safe Mode" itself at the top of the list. Use your arrow keys if necessary to select this top option, then press Enter.
If RPCSS.exe is not needed in Safe Mode, or if whatever else that is unsuccessfully calling it is not needed, your system may load up into a basic Windows Mode, no desktop image, larger icons, lower resolution, with "Safe Mode" displayed in each corner of the screen.
Often that can fix things. Once loaded, try a restart from the Start Menu > Shut down options and let Windows attempt to load normally. If that works you're away, and you can backup those files!
If not, it gets a little more problematic. The other possible options are;
1] Back to Safe Mode list of options, then select "Last Known Good Configuration". This will attempt to load a backup of the registry.
2] Back in Windows loaded into Safe Mode, attempt to run SFC, the System File Checker. You may need the XP CD, but even then SFC may not work in Safe Mode. if not you can tell the system to run SFC at the next bootup, called sfc /scanonce , (note the space before that slash). Both sfc and sfc /scanonce are initiated by going to Start > Run, type in cmd and click OK. In the Command Prompt window, type in sfc /scanonce and press Enter. restart the system.

3] If both of those fail, then you are looking at disaster recovery. That means a reinstall of XP. To save your files, I suggest using an Operating System on a CD. Such things exist and I've used Knoppix Live CD in the past myself. It is a Linux Distro that wholly resides on a CD and which you start the computer with the CD inserted. Knoppix will load without changing or adding any files on the hard disk, and it will allow you to copy all of your files onto some other media, eg a USB external hard drive.
The latest Ubuntu Live CD is better so I am informed.
Then you reinstall XP.
If all of that fails, then sadly it's the repair shop, or some data recovery service, but hopefully one of those will work.
Just as an aside. RPCSS.exe resides in the C:\Windows\System32 folder. If there is another RPCSS.exe located elsewhere on the hard drive, then that may be a virus. A scan of your anti-virus in Safe Mode may find it.
Hello, I am new to CNET and not exatly sure of the rules. So please advise me where I am incorrect.
I am running on Windows XP Professional on a Toshiba laptop.
I tried to boot my system up yesturday morning (with no previous error(s)) and my system gets stuck on "RPCSS is starting..."; I looked on another thread at a similar problem, the only difference was that whomever had the problem before, their system would eventually get passed it.
I have left my laptop on all night to see if it would get passed this screen, and nothing changed.
I have concidered rebooting my laptop with a different version of XP, but as I am a website designer, I have many clients' projects on my laptop; I never thought to back them up because my laptop is fine - so I thought!
I hope there is a reasonable solution to this unexpected problem.
Thank you for any advice you may give me, any help is grealty appreciated.
