Intermittent Network Share Slowdown

Hi

Server is a HP ML310 G5P - Dual Core Zeon 3Ghz, 8GB RAM, RAID 10. All connected via an Allied Telesyn Gigabit switch.

SBS 2008 Std fully updated

Supporting about 5 users. Server is as far as I can see heathly, only about a year old. Loads of disk space, responds well, etc, never had any previous problems.

Yesterday my clients reported to me that each of them had problems with the shared drive:

1. Taking an age opening any files (mainly office docs, maybe few KB in size)
2. Double clicking a file, and nothig happening
3. Taking a long time to renumerate files in drive

etc...

Also, 1 isolated complaint of Outlook 2007 playing up, saying "Need Password" (even though the user's password was valid). After entering password, Outlook states online but rapidly switches between "updating folders" and "All folders up to date" non stop. Tried a reboot.

Mostly after 10 mins of so the issues disappears for a while. Happens 2-3 time throughout the day so far.

Only 2 warnings in the event logs are:
Application
Source: IIS-W3SVC--WP
Event ID: 2262
Level: Warning
Description: ISAPI 'C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'.

And

System
Source: WAS
Event ID: 5013
Level: Warning
Description: A process serving application pool 'MSExchangeSyncAppPool' exceeded time limits during shut down. The process id was '10120'.

Any ideas?

Check AV schedule scans on server and workstations, exclude any network drive scan on clients. See if that solves the problem?

hongeditAuthor Commented:
Server has scheduled scans for the evenings, whilst clients do not have scheduled scans but realtime protection enabled instead.

Will see if excluding network drives has any effect.

Although this has been in place since inception, and the problem only just started happening...known stranger things though, esp with AV!

Shall have a go and wait to see if it improves. Unfortunately not easily recreated so just have to wait and see.

Maybe an update on the server has affected it. Look through the updates and their install dates.

I had the same issue when users' were trying to access mainly office documents on a network Share...What version of Office are your clients running?

Also, what Operating system are they using?

Have a look at this link. We are not running SBS (recently upgraded) but your problem sounds a lot like the one we were having. The link below helped me out. Especially, Bradford Fishers.

Ok, absolutely. We have the same client setup & so far I have tested the reigstry, and SMB fix on 4 client machines and it has fixed the problem.

I mean to say the post from swb_mct fixed my issue and not Bradford Fishers (referring to the posts in the link I sent you)


You don't happen to run Trend Micro as your AV do you?

hongeditAuthor Commented:
No, we dont use Trend.

I'll give the fix a go tomorrow when people are back in the office - shall let you know!

In fact, I'll do the server bit now and reboot tonight.

Llacy80Commented:
Cool. I hope it works...Keep in mind that article does not refer to SBS2k8 so as far as the registry changes go I would assume it is the same and that it should not cause any issues but you never know so make sure to get a good backup before making the reg changes on the server.

In fact I only made the registry change and SMB change on the client machines and not the server yet and so far so good (2 weeks).

hongeditAuthor Commented:
The reg change on the server was indeed in the right place. I did a backup anyway.

Time will tell!

Llacy80Commented:
So did you have any luck with the registry change I mentioned? Has it seemed to help so far? I hope so.
