I configure something wrong in windows XP through gpedit.msc and restart the computer after that 80% of services of windows are stopped I tried manually to start that services but group dependencies services error 1068 comes. Then I saw that RPC service is also stopped then I try to start it but u could not start RPC service on local computer access denied error 5 comes. I am not even go to the properties of services to check that what's the prob. Now Lan, Audio, taskbar and lots of other things r not working. Plz look into this matter ASAP.

A few focused recovery and diagnostic steps that often fix an RPC/service failure caused by policies or damaged permissions.

As described, policy or service-permission changes can stop many services and cause Error 1068 / Access denied (5) when you try to start RPC. Try non-destructive recovery first: boot to Last Known Good Configuration (press F8 at boot) and, if that fails, boot Safe Mode and run System Restore to a point before the gpedit change. Those two options frequently restore the service-related registry state.

If that doesn't help, log on as an Administrator and collect diagnostics from Safe Mode (Command Prompt). Useful commands:

tasklist /svc
sc query RpcSs
sc qc RpcSs
net start RpcSs
sfc /scannow
chkdsk /f

tasklist /svc maps services to each svchost.exe; sc query / sc qc show RPC status/config; net start attempts to start it; sfc checks/repairs protected system files (XP may prompt for the install CD); chkdsk verifies disk integrity.

If RPC still returns Access Denied, it's usually a permissions/policy problem. Back up the registry first, then inspect
HKLM\SYSTEM\CurrentControlSet\Services\RpcSs permissions in regedit and ensure SYSTEM has Full Control. Check Local Security Policy → Local Policies → User Rights Assignment for accidental entries in "Deny log on as a service" or misconfigured "Log on as a service". If a System Services policy in gpedit was changed, revert those entries or reset local security policy to defaults (proceed carefully).

As suggested, inspect which services are hosted under each svchost. As advised, restore points are often the quickest fix. And as noted, don’t forget malware — older worms (Blaster family) targeted RPC on unpatched XP; an offline/rescue scan is worth running. If core system files or ACLs are badly damaged and recovery fails, back up data and consider a clean reinstall to guarantee system integrity.

I actually cannot guess what you have done... is svchost.exe running... can you see instances of it in task manager/processes? I actually don't know if windows can even start without it, and I don't know how you could interfere with it via gpedit.... but...

svchost.exe is running

start/accessories/system tools and do a system restore back to the a day before you used gpedit to change SomethinG.

Thanks to all who reply to my Thread but I solve this prob myself just to replace these files (svchost.exe n explorer.exe)
