Topic: One domain doesn't work at certain times, others do.

[darkcrimson]

The server I am working with has been up and running for about a year now with SME Server 6.0.1-01 but lately, as of ~3 weeks, I have noticed that the domain which is specified as the primary domain returns a 404 not found at certain times of the late afternoon and night when trying to access it from outside the network.

This only happens at night and late afternoon it seems and almost seems to be almost random.

The odd part is we have several other domains on the server (and same IP) and they DO work even when the main domain is down. And I can access the FTP server for the domain even when I cannot view it.

I did not change any settings that I can think of that would cause this problem and I have no idea what is causing the 404 on one domain only.


Any one know what could be causing this?

Thanks!

hmmmmm....

possibly a client dns problem? what is your dns server? can you resolve the correct pdc when this happens?

[darkcrimson]

I am not quite sure what you mean when you ask what is the dns server? I also do not know how to resolve the pdc.

for refference, the domain I am talking about is:  http://www.hmsys.com --as of 5:40pm eastern time, it is NOT working (again)

any ideas?

your local network is going to have a dns server (could be sme, windows server, or router)that manages names locally. if you have several dns servers, it's possible one is misconfigured. this is often the case when a w2k server is not pointing to itself as the dns. it drops out. then it kicks back in periodically.

Any ideas how I can check these settings?

Also-- I believe we are running a SME server on unix.. but the rest of the office computers are on 2000 (where I access the server manager software)

[kruhm]

i'm talking about checking your dns server's on the windows clients

-click START>RUN>CMD>OK
-type ipconfig /all

Your dns servers will be listed. Is it your SME server or another box?

when I check the server settings with myphpadmin, it says we are runing a SME server, under ipconfig it says:
