Server intermittently loses ability to load websites

The symptoms on the server (SBS 2008) are that the programme for sending SMS messages stops working, as does my usual remote desktop (using Kaseya).  However, I can connect to a workstation and then remote desktop onto the server.  The server can resolve domain names in the command line and ping them, but it will not load any websites giving the error "Internet Explorer cannot display the website".

The quickest solution to date has been to reboot the server at which point the problem goes away again in some cases for over month but it has just returned again.

Anyone any ideas?

Thanks, Chris

Hello,

Sounds like an issue with DNS.  Are there any errors on the SBS referencing to DNS Errors? Any errors at all thats worth mentioning?

Does this happen on just one machine with the SMS software on or is it all the machines?

Can you access the Internet from the Server locally when it does this?

Hi Scorpeo,
DNS Server errors 404 and 408 have been appearing since 8:30 this morning.

404: The DNS server could not bind a Transmission Control Protocol (TCP) socket to address 0.0.0.0.  The event data is the error code.  An IP address of 0.0.0.0 can indicate a valid "any address" configuration in which all configured IP addresses on the computer are available for use.
408: The DNS server could not open socket for address 0.0.0.0.
Verify that this is a valid IP address for the server computer.  If it is NOT valid use the Interfaces dialog under Server Properties in the DNS Manager to remove it from the list of IP interfaces.  Then stop and restart the DNS server. (If this was the only IP interface on this machine and the DNS server may not have started as a result of this error.  In that case remove the DNS\Parameters\ ListenAddress value in the services section of the registry and restart.)

I have been to the list of IP interfaces and it is set to "Listen on All IP Addresses".
 
If this is a valid IP address for this machine, make sure that no other application (e.g. another DNS server) is running that would attempt to use the DNS port.


NTFRS 13568 could be the cause.  Although this is a standalone SBS 2008 server so I'm not sure what it's replicating with.  Have applied the fix found here:
http://social.technet.microsoft.com/Forums/en/smallbusinessserver/thread/19b25562-bd6b-4b9e-93b9-948611213982

Trying to open AD Users and Computers says that the server is not running, so continuing to investigate.

This is the only machine it happens on.

So now the Internet it working again on the server but the DHCP server will not start and returns event 1008 "not enough storage space", although there is about 30Gb free on the System volume.
Also DNS says it is running but I cannot access the DNS snap-in.
This post mentions a hotfix, which although definitely similar I'm not certain is the problem:

Any further suggestions?

Run the Fix my Network wizard in the SBS console. Report back any errors that it finds/fixes.

1. could not configure router
2. DHCP service is stopped
3. DNS server is not listening to the IP of the primary network adapter
4. DNS zone is missing
5. reverse DNS zones is missing or invalid
6. Internet domain name is not configured

I could not tell which of these was a primary and which was a secondary problem.  I decided if I could get DHCP started then the others might sort themselves out.  What do you think?

So I didn't get this resolved before needing the DHCP server so I had to reboot the server which subsequently brought everything back online.  I ran the Fix my Network wizard again and it came up with a minor issue with DNS - it was listening to an additional unused IPv6 address.  And that was all, nothing further in the event logs. So it looks like it's disappeared again, but I suspect may return in a month or so.

Cheers

Sorry I must have missed your previous reply!

1) Don't worry about this - It just means that your port forwarding must be applied manually.
2) Yes that will need starting.
3) Do you have two network cards? -
4) Concerning - I would have fixed with the wizard
5) The above (4) caused this.
6) You need to run through the Internet Domain Name Wizard if you haven't already.

Glad the reboot sorted it.  If this does happen again, re-run the fix my network wizard and see if it repairs it. Double check that nothing else on the network is providing DHCP (this will stop DHCP from working on the Server).  Keep an eye on the DNS Logs.

Scorpeo,
Thanks for the reply - I'm aware that those problems are "concerning", "need starting", etc. but those are exactly the problems which seemed to start 'randomly'.  All those services run perfectly well and then maybe once a month the gremlins come out.

So unfortunately I can't give you any points as the problem has not been solved, only the symptoms.  Unless the problem was caused by the Journal Wrap Error, in which case that has been solved.

Many thanks,
Chris

Journal Wrap Error wouldn't cause your problems.

If it happens again then I suggest you double check all services to see if the automatic ones are started.

So this problem has just reoccurred:
1. Fix my network states: DHCP service is stopped, DNS zone is missing.
2. Internet works on all workstations but not on SBS server.
3. Event 1006 DHCP-Server states: "DHCP service failed to start as a RPC server. ... Not enough storage is available ..." (C: 17.4Gb free)
4. Event 408 DNS-Server-Service states: "DNS server could not open socket for address 0.0.0.0..."  AND Event 404 DNS-Server-Service: "DNS Server could not bind a TCP socket to address 0.0.0.0..."
5. I use Kaseya to monitor the server and at 18:50 is stated the server was offline, at 18:40 there is this event: Tcpip 4227: TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate..."

I shall contact Microsoft but any further help you can offer would be appreciated.  
Thanks,
Chris

Hello Chris - What did you find on Tcpip 4227.  Kaseya also reported this event to me today on one of our SBS 2008 machines.

Thank you - MrCannon

I didn't get anywhere with this.  Microsoft haven't been able to help so far.  The main problem for me was that DHCP crashed and the print server stopped and Internet access from the server didn't work.  No idea why.  If this is not the case with you then you probably have a different problem.

When another of our engineers looked at this he recognized that the particular network card was known for instability and recommended replacing it.  After doing this the problem has not re-occurred.

I've logged this solution so that anyone else encountering similar behaviour may know the fix.  In the end it was a third party that found the solution.
