This morning, 2 of our DELL Optiplex 760 (we have 4) starting having issues with Windows. Their network connection is gone. The Windows Start bar dissapeared and I cannot seem to add/remove programs even though I am logged in as the local Administrator.
These computers are running Windows XP SP3.
Here are some highlights of the issues these computers have:
If I double click the Microsoft windows Network in my Network Places:
I get this error: Unable to browse the network
The network is not present or not started. Our Mapped drives are gone.
If I right click My Network Places, nothing shows up.
When going through folders, I can select a file and copy it, but I cannot paste it anywhere. If I right click and choose Paste, the paste option is grayed out.
The Windows Start bar is gone. I can see only the upper border and I cannot bring it where it was before.
Add Remove Programs loads up, but I cannot remove any programs.
If I try System Restore, I get this message:
System Restore is not able to protect your computer. Please restart your computer and run system restore again.
I checked the registry Windows Current Version Run and I did not notice anything unusual.
If I use MSCONFIG and I try to uncheck a service (like Java) I get this error:
An Access Denied error was returned while attempting to change a service. You may need to log on using an Administrator account to make the speficied changes. I am logged in as the local administrator, though.
The last thing I remember this computer was able to do was a java update this morning right after I woke it up from Stand By mode.
The weirdest thing is that 2 out of 4 DELL OptiPlex 760 are having the same problems. The other 2 and the rest of our network computers are fine. These 2 Dells are some of the newest computers we have in the the office.
