asked on 

Exchange OWA and Outlook access over WAN don´t work nearly every day. Outlook via LAN works fine

HI,

nearly every day we are not able toaccess the exchange over OWA or by using Outlooks outside the LAN. Restart the Exchange-services don´t help. There are no helping entries in the eventlog. If i make a "iisreset /restart" everything works fine till next time.
We have a SBS2008 with Exchange2007. All Updates are installed.

Any idea ?

Are you using any sort of mail firewall or anti-spam that could be eventually killing it after IIS restarts?

There is Kaspersky installed. Customer wants so...
Antispam there is nothing. Firewall only KAspersky. But it works for ours and then it stops. So i think this couldn´t be a firewall-problem, o could it ?

It very well could be. Have you checked the Kapersky logs there when it stops? If it works internal but not external then I would assume there is some sort of firewall/port issue gumming it up.

Sorry its been a while. The problem ist still there. We have already uninstalled antivirus. I made a netstat with this interesting output:


 Es konnten keine Besitzerinformationen ermittelt werden.
  TCP    192.168.2.250:443      tmo-113-94:11611       HERGESTELLT

 Es konnten keine Besitzerinformationen ermittelt werden.
  TCP    192.168.2.250:443      ipservice-092-209-079-174:62827  SYN_EMPFANGEN

 Es konnten keine Besitzerinformationen ermittelt werden.
  TCP    192.168.2.250:443      ipservice-092-209-079-174:62828  SYN_EMPFANGEN

Any idea what this could be ?

Means

there could no information be found about
ownership

Hergestellt = connected

Syn_empfangen = syn_received

there are two services listening on local port 443 it looks like for me. Or am i wrong  here?

Those programs where ok. I realized that Sharepoint services throw errors every 3 seconds because the db of sharepoint was killed in former times. We dont use sharepoint. So i uninstalled sharepoint services and from this everything was fine...
