Visualizer Forums - View Single Post - lsass.exe System error: The endpoint format is invalid.

I'm also having this problem.. on more than one occasion.

I have tried the XP Home Repair (twice) with uncertain success. I say this because it is not clear that the repair and updates were of any help in correcting the problem. In fact, I was only able to recover to normal state after manually editing all the boot logs that were large and reducing their sizes. Miraculously, I was able to boot normally after doing this.

My system has been running very well the last couple of weeks. In fact, it was running so smoothly and quickly, I took a system restore checkpoint two days ago so I'd have a place to fall back to if any problems arose. As expected, my old lsass.exe error reappeared this morning. (I shut down every night.)

As you are, I am able to boot in safe mode. I have XP Home on an ASUS board with ATI graphics, dual monitors. 1g ram. Rolling back the System Restore to the last good checkpoint had no benefit. Still have the error. As you, no device conflicts. I have dual 120gb drives in RAID format. I did install an updated raid driver recently, but have had several successful boots since that time.

This is really perplexing...
