ntbtlog.txt is very large(5800 lines)

August 25, 2013 at 03:26:28
Specs: Windows 2000, P4 2.4mhz 2GB ram
One of my computers (Win2000) takes 2 minutes+ to boot up. I checked ntbtlog.txt and found it has about 5800 lines (each line is a file being loaded). My other Win2000 computer has a normal boot and the ntbtlog.txt has 257 lines. In the first ntbtlog.txt, these 257 lines are repeated about 50 times.

I don't know how this happened, but I'd like to know how to fix this problem. Can someone help me with this.

Re-install Win 2K ?

Re-installing Windows 2000 would be at the end of my list. I'd like to understand what caused this problem and perhaps find an easier solution.

It appears this computer is not booting in normal mode. See the link below.

From that link in Tom's Hardware I couldn't figure out what you meant by "it appears this computer isn't booting in normal mode". What mode are you suggesting that I might be booting up in, and how would that increase the number of loading lines 50 fold?

The excerpt below is from that link. Other Googled threads also indicate the same. Is the boot option set to step by step or last known good configuration.

I think your can delete the log without harm.

"Take a look at the ntbtlog.txt located in the systemroot. Boot logging is
enabled when using any Safe Mode option or by adding /bootlog switch to the
boot.ini file".

All the ntbtlog.txt does is report/confirm there's a problem, it isn't the problem itself as far as I know. The problem is that during the bootup all these drivers and dlls are loading over and over and over (50 times). I had the slow boot problem before I added the bootlog switch in boot.ini .

Now that I see a problem, I'm trying to find out what's causing it. Where is there a list the drivers and dlls that load during bootup. Is there a corrupted file somewhere that's causing this problem. That's what I'm looking for...and I don't think deleting the ntbtlog.txt file will make the problem go away. It would be nice, but improbable.

Have you changed any hardware prior to this issue starting? As I stated, the log file is only created if Windows doesn't boot correctly. You didn't answer about how the computer is booting. I suggest you delete the log file and see what happens.

Are you sure about that...I've read that you set the boot to log just because you want to see what's going on, I haven't seen that it only occurs when there is a problem.

My boot is slow, occasionally chkdsk runs but doesn't fix any files. Other than that there is nothing wrong with the boot, no BSODs. And no recent hardware changes.

I deleted the ntbtlog.txt and the next boot it had about 132 lines. Ten boots later it have ten times that. So I think I've been interpreting this all wrong, the ntbtlog.txt is just appending what it sees each time instead of overwriting the original file. The slow boot must be coming from something else..

The Event Viewer shows an error after boot that "WinMgmt could not open the repository file". I've been trying to get help on that in another thread, but no luck so far. Do you know anything about this?

My mistake. The log is created as long as boot logging is enabled. The log shows what drivers are loaded.

Can you boot into Windows safe mode? If so, and the computer boots in a normal time frame, you can compare the files from a safe boot and a normal boot.

Didn't know anything about repository files. Google is a great tool though. I see references to Oracle and Moodle.

See the link below for another slant on your problem.

In safe mode it still took a long time, and ntbtlog.txt had 167 lines...compared to the regular boot where ntbtlog.txt had 257 lines.

I've been using msconfig almost as long as I've used Windows 2000. I check it all the time so there are no surprises running on my computer at any time.

I'm looking for a program like bootlog XP that will show the loading times for each item loaded during the boot. Bootlog XP doesn't function correctly on Windows 2000, alas.

Are you running SP4 on your 2000 install?
