Need a quick answer! 1

I upgraded our Exchange 2000 server to Exchange 2003 on a new server. Everything went OK, except I'm having 2 problems:

1. We cannot receive inbound mail over about 4 meg in size. I know the default limit on Exchange is 4096, but I changed it to 10 meg. I even restarted the server to make sure all services were restarted. Still no go.

2. This was a problem on the old server too: We allow access to OWA from the internet. I have the default web site on the mail server redirected to \exchange so internet users can go to mail.domain123.com to get to OWA. When they go to login they have to type domain123\username in the user field or else the login fails. I have the correct default domain set in the directory security on the OWA site, but it doesn't seem to work.

Any help would, uhhh, help. Thanks.

I'd like to see the answer as to why my users now have to type in "domain/username". It used to just be username for login. I've had a few Exchweb directories get corrupted on me though in the last few months. After those fixes is when this minor issue began.

Good luck though.

Question 1
Do you perhaps have a firewall that is blocking the file sizes such as ISA server?

I would try setting the value back to default, reboot, then reset to your 10MB limit and reboot.

Question 2
From MSKB 820378:
If you do not want to specify the domain when you log on, create a custom Logon.asp page that includes the default domain (either visible or hidden). You can also display a list of the domains that the server supports.

The following example code illustrates how to create a custom Logon.asp page. To use this code, replace both instances of <FORM> in each language-version of the Logon.asp file with the following code.

Note You must replace both instances of <FORM> with this code because one instance is for rich experience and the other instance is for basic experience. This replacement is required for browser compatibility. Also, if you make a custom Logon.asp page, users will no longer be able to log on with a user name of domain\user name. If they do this they will actually be passing domain\domain\user name.

<script Language=javascript>
 <!--
  function logonForm_onsubmit()
  {
   if (logonForm.username.value.indexOf("@") !=-1)
    {
     return true;
    }
   logonForm.username.value = "<name of NetBIOS domain here>\\" + logonForm.username.value;
   return false;
  }
 //-->
 </script>
 <FORM action="/exchweb/bin/auth/owaauth.dll" method="POST" name="logonForm" autocomplete="off" onsubmit="logonForm_onsubmit()">

I hope you find this post helpful.

Regards,

Mark

Thanks, Marc, I'll try the custom logon page (as soon as I get the other problem fixed). I have Microsoft on the phone now, and I seem to have stumped them for now. (I feel it reflects badly on me if Level 1 support fixes my problem.)

---Update----Message Size problem fixed. When you have an email scanner (Brightmail) between your firewall and your mail server, the scanner uses the IIS SMTP service on the scanner box to pick up the mail and pass it to the email server's SMTP service. The SMTP service has a default message limit of 2 meg. You need to change it in the virtual servers settings on both the spam scanner machine as well as the email server. I didn't encounter this in any of the docs I read. Microsof should put this in their KB.
