SBS2003 Network issue?


Recommended Posts

Guest ratman and bobbin

Hopefully this is the right group.

Quite suddenly in the middle of this week, all users started reporting

difficulties accessing the Internet (404 errors) and additionally could not

access a unix server application. Then their Exchange sessions started

dropping out and then reconnecting at frequent intervals, synchronisation of

folders became intermittent too.

 

browstat shows the server as the master browser and I can find no errors

anywhere, although it will pick up the unix server any attempt to browse it

via Explorer results in an access denied error. This smells like a DNS issue

(just a hunch) but the config looks ok.

 

Now staring at a complete rebuild of the server and not relishing the

thought (seems a sledgehammer to crack a walnut) type approach.

 

Any comments suggestions hints tips gratefully received!

Hello ratman,

 

Run dcdiag /v, netdiag /v against the DC. Also post an unedited ipconfig

/all from the server and one problem client.

 

Best regards

<adding microsoft.public.windows.server.sbs group>

 

Do you have ISA installed and do you have SBS R2 with WSUS?

No ISA. WSUS installed but not working properly (another problem for another

time). Microsoft Windows Server 2003 for Small Business Server + SP2

IPConfig from both the server and a client, as has been requested.

 

and try http://www.sbsbpa.com, run the BPA against the server. Could be one of

several things it will pick up.

Re: SBS2003 Network issue?

 

Have run sbsbpa and it highlighted a number of issues - including task

offloading and EDNS enabled. Have corrected both issues and will have to

wait till Monday am

to see if it provided a fix.

 

One thing still puzzles me and that is why has the server run for over a

year with no problems and then suddenly decided to throw a wobbly?

Re: SBS2003 Network issue?

 

Sometimes problems can remain unnoticed until the server reaches a threshold

of traffic, or the incompatibility gets exposed because of an update

installed on the client, or a myriad of other things. It isn't uncommon.

Re: SBS2003 Network issue?

 

Happy to report problem solved. If you send me lots of money I'll tell you

what it was! LOL!

 

It was a network issue and nothing to do with the server. After applying the

fixes and diagnostics suggested, the Server appeared fully functional, but

the problems remained. So moving on I decided to check the network for rogue

devices or problems. This particular network has 2 16 port Switches and 3

smaller hubs for localised sharing. Each unit was removed from the network

in turn and when a small Linksys 5 port hub was removed, the network sprange

back into full life. This particular hub is now decorating my wall of

infamy.

 

My appreciation to every one who bothered to respond and provide useful

suggestions and hints. I have learned from this experience but I am now just

a little older and greyer because of it.

 

Thanks!

Geoff
