Slow login problems

[Guest]

We have a corporate network with +- 500 XP pro workstations. For almost half
of them loging on takes 20-45 min. After solving a lot of errors found in the
event log I have run out of ideas.

As you can see there is one DHCP error almost every time they log on,
however this error doesn't seem to slow down the login.
The thing that puzzels me the most is why there is so much time needed for
the Service Control Manager events. Each time "The Windows Installer service
entered the stopped state." OR "The SMS Process Event Driver service was
successfully sent a start control." events the system takes a long time to
get to the next event.

When I checked the systems that aren't having problems I noticed that they
take less then 1 min to go through all of the Service Control Manager events.

So I am guessing that this is where the problem is situated, but can't find
any info about it on the net.

On a single computer I would look at availability of sufficent RAM
i.e to what extent is a machine using the pagefile. I would also
check that all third party drivers are fully updated.

What happens if you create a new user profile for a machine? Do you
see a quicker boot?

Are you running Disk CleanUp and Disk Defragmenter.

Do all machines have over 20% free disk space?

Are anti-virus programmes scheduled to scan on booting and some at
other times?

Can you post a copy of the DHCP warning?

Ok, to answer your questions:

The RAM can't be the problem since some of the systems that are experiencing
the problem are brand new workstations with more than enough RAM, furthermore
some of the older systems with a low amount of RAM don't have the problem.

The same thing can be said for the drivers. A lot of the systems where
bought at the same time, so if it were a driver version problem it would
happen to all of them, but that isn't the case.

I have checked our virus scan and it isn't scheduled to run at startup.
furthermore i would expect to see some info in the eventlog if the Virusscan
was running.

The DHCP warning isn't the problem, we made some changes and fixed that
error, but this had no consequences for the slow booting problem.

The only thing we haven't tried yet is logging in with a different profile.
The strange thing is that if we reboot the systems during the day booting
goes a lot faster., It seems that it only takes so long the first time they
log on each day.

Disc space can't be a problem either since some of the workstations have
more then 100GB free space.

Are all computers in the network using the same operating system,
particularly the computers the problematic ones are connecting to?

Until you know the cause of the problem or problems you should not
be too quick to rule something out. You should not assume you have
only one problem. That something is brand new or bought at the same
time does not mean that they will act the same way or have exactly
the same components. Most new computers when sold as brand new
rarely have all the latest third party drivers. Each computer will
be used by a different user and each user rarely uses the computer
in exactly the same way.

What services are loading later than others?

Are there any yellow question marks in Device Manager? Right click
on the My Computer icon on your Desktop and select Properties,
Hardware,Device Manager. If yes what is the Device Error code?

Try Start, Run, type "sigverif.exe" without quotes and hit OK. What
drivers are listed as unsigned? Disregard those which are not
checked.

Are there any diiferences in programmes loading at startup?
