Laptop logon times very intermittent

[Darylrese]

Hi all,

 

When i started at my school, all staff had roaming profiles and the more they put on their desktop, the longer it took to logon. Some users couldn't logon at all in a location other than their own room as it took too long to login.

 

Now i have used redirection policies for My Documents / Desktop / Favorites to a network location and changed their accounts to local profiles. On desktops it's really quick to login after making these changes and takes less than 30 seconds to logon even in a different room.

 

However, am experiencing very intermittent logon times when it comes to staff laptops. Sometimes it takes a matter of a few seconds to logon, other times it can take up to 25 mins! It seems much slower to logon after a reboot than if you logon / off without shutting down.

 

I cant see anything obvious in group policy but its faster when a user logs on off the network.

 

Unfortunately we use Offline Files and i have read some settings for this can cause issues?

 

Many thanks

When you say slower to logon after a reboot, is this definitely a graceful reboot and not that the laptop has been forcibly powered off (holding down the power button) and then booted up again?

 

Forcibly shutting down can cause long login times at next login due to WMI repair...

Have you enabled verbose messages on startup so you can see where the sticking point is?

Yes certainly is a clean reboot. I tried it for myself.

 

Logged on and off no problems very fast (under 30 seconds) then reboot and sometimes still quick, other times very slow (15 mins +)

 

I haven't enabled verbose mode yet will do some testing on that when I get in today

They're probably sitting there looking for the roaming profile.

 

Like @sparkeh says, enable the Verbose Messages GPO on their OU (Computer settings) to see.

 

Or they might be loading up a huge local profile.

 

Try deleting all the local profiles and do this ...

Offline files caches network files locally and has to synchronise. I'd advise that you turn it off if you don't need it.

You should try windirstat on the suspect profile folders. Possible that th AppData folder is filling up.
