How did you look for the Event Log service?
There are various ways to get to the Services console, and one is;
Right click your "My Computer" icon on the Desktop, select Manage. In the Computer Management console, expand the "Services and Applications" option on the left, then highlight services. Make sure the Extended tab on the right is selected.
The Event Log should then be listed. It should be set as Automatic. If it isn't, right click the entry and select Properties, and in the Properties window, change the Startup type; to Automatic.
If the entry isn't there, do a search on your computer for "C:\WINDOWS\system32\services.exe".
If that isn't there, then you will need to get it back. You can try "scannow /sfc" in the Start > Run command, (note the space between the w and the / ). This will scan all of XP's protected files and try and replace them if necessary. Make sure you have your XP CD handy.
If Scannow finds and fixes any problems, reboot the computer and see if the Event Log service has appeared. If not, then you are looking at a "Repair Install", to replace all the System files. Guidance here
I hope this helps.
I have been having an ongoing problem in being able to install programs (diskeeper and Symantec) after I have downloaded them. Their advice to me has been to double click the "Event Log" in my Services list and set it to automatic.
I have just realized that the title, "Event Log" does not exist in my list and I think that may be my problem. Recently, I upgraded my Windows XP Pro from a pirated version by paying for and installing the Genuine Windows XP Pro version. I had then installed SP2. I wonder if in all of this I have lost the Event Log heading and if anyone can tell me how I can get it back.
