Oracle 8i Intelligent Agent Service problem

Hi!
We successfully installed Oracle 8i (8.1.7 ee) on Intel P-IV (Xeon) server running Windows 2000 Advanced server (Service Pack 2). It was working properly until now. There was no problem in implementing the tricks useful in installation. After that, database service "OracleService<DBName>" presented problem by not automatically starting on computer startup but it was tamed by "Oradim" command added to startup folder.

All was going smoothly for about a month now but when I rebooted the server PC yesterday, the service "Oracle<HomeName>Agent" failed to start. Along with it the DataGatherer and TNSListener services also failed (Only db service OracleService<DBName> starts but very very slowly). The Windows Event Viewer descriped the problme for Agent service as ,"The Oracle<HomeName>Agent service terminated with the following error: %%3221356551 ". The Event ID is always 7023 for this error. The rest of services just don't give any error codes. It is also stated that nothing has been installed/Uninstalled on this PC in the last several days and no configration changes, in tnsnames.ora, sqlnet.ora, listener.ora, win registry has been made. The TCP/IP configration are intact and NTFS folder and file rights are properly defined.

Starting the service using "Net Start <service_name>" also failed with the message,"System error 7 has occured, Storage control blocks will be destroyed".

Searching online, I also performed some steps in correcting the problem like backup and delete all *.q, snmp_ro.ora, snmp_rw.ora, services.ora files. But to no help. The log files in Oracle_Home\network\logs also dont record the problem even after setting the trace level to Admin or 16. The Agent service simply refuses to start...

Reinstalling Oracle (over existing one, not first removing it altogether. We simply cann't do this now for data loss!!!) or just the Intelligent Agent itsself using univeral installer also fails at the end when it tries to start the intellegent Agent Service Oracle<HomeName>Agent. This time the error described is "O/S error in starting service".

Is this something to do with Xeon server coz the same Oracle 8i is installed much before than this on another P-IV server (not xeon) running the same Op system and it never presented us this problem todate. Its also worth mentioning that this problem occured before as well, on the second day we installed Oracle 8i the first time on Xeon. Since there was no data then, we simply removed oracle, cleared registry and started all over again BUT now it cann't be done.

Any help shall be highly appreciated.

With Regards, Rashid.

Thanks everyone who stops by this thread... I got the solution and its working now

The oracle homefolder was accessable to Administrator only, when I also added 'Everone' to the permission list , all started working normally. Everyone is dangerous to add but it is good for now....
