Front End Exchange 2003 OWA for a Back end 2000

Hey everybody,

At the minute we're in the process of upgrading our 30 odd servers to
Windows Server 2003.
The Domain Controllers are still running Windows 2000.
My question is :
Can I install an Exchange 2003 OWA on a Windows Server 2003 to connect to an
Exchange 2000 Server in a Windows 2000 Domain (Native Mode)

Do I have to upgrade the whole domain first ?

What about notions of Front End / Back End ?

We would like to do this to benefit from the new OWA (As it's sooooo cool

Thanks for your replies,

You can use an E2K3 FE to connecto to an E2K BE, but you 
only get OWA 2K.
They say to upgrade the FEs first, but I'd suggest you 
install new FEs with E2K3 and then decomission your old 
FEs. This is purely financial since you needed E2K 
Enterprise for an FE but only need E2K3 Standard for an 
FE. You'd be wasting licence cash by upgrading. You can 
then use your E2K Enterprise licence to use somewhere 
else (either as-is or by a cheaper upgrade to E2K3 Ent)

Maintenance on Exchange
Hello all, I have been looking over the threads here and did not see any real input on this subject, performing maintenance, defrag the database, on Exchange 5.5 and 2K. I am also running through TechNet and find all kinds of articles on how to do defrag and compact the databases but nothing that offers any insight into doing this after so many transactions(e-mails sent and received either internal or external), or over a period of time. I am also finding the same thing on backups. All kinds of articles on how to do it but nothing that says here a recomended way. I guess someone ...

Exchange server unreachable after being moved
Hello, people. I hope you could help me with this issue. We have two Exchange 2003 servers (A and B) in our organization. The server A is the main server and as it was needed, server B was added in the same Administrative group in the same site. But the last server (B) was ment to inhabit in another country, so this server was sent to my coutry. Now they both keep a constant communication via VPN. The problem is that since de the server is here, only internal message can be delivered (among mailboxes in this server) but not messages between servers (I mean, a message sent from a mail...

Exchange 2003 SP2 Q
Dear all, I have a few fundamental questions. 1) Can Antivirus software for Exchange Server that uses AVAPI Version 2 corrupt the store database? 2) Is it possible for MAPI client like outlook 2002 and 2003 corrupt the store database? 3) Can third party backup software corrupt the store during backup? Thanks. Regards, Kueh. 1. I've never seen this happen, though I wouldn't say it is impossible. 2. Same as 1. 3. I've never seen the backup software itself corrupt a mailbox store. Usually, backup software is one of the mechanisms to let you know that there is corruption...

Store.exe crashing on 2 Exchange 2003 servers

Validation Confusion-Excel 2003
On a timesheet I need to ensure that when I enter in the times of a the DAY shift that it is on or after 6:00 am. The finish time is not important as the start time dictates the shift. For example, someone may start at 7:30 and work thro to 3:30 (or 15:50), this equals a day shift. I may have someone else who starts at 6:00 am and finishes at 10:00 am, this also equals a day shift. I also need an AFTERNOON shift that starts at 12:00 (Noon). I believe if I have the answer to the day, this will come easy to me (that is if the Noon time doesn't become a hinderance??) I also need ...

Exchange (unofficial) service pack 5
During 2003 in an effort to correct an Information Store Hung Thread, while stopping the service, in Exchange Server 5.5, I was provided, by Microsoft, a partially developed Exchange SP5.

He needs to install the appropriate Service Pack for the restore to work, and I am trying to locate the unofficial Exchange SP5 to help him. Can anyone help?

Port 25 telnet on Exchange 2K3 servers
Hi, Installed 3 new Exchange 2K3 SP2 for a client the other day, but unable to telnet to port 25, even on the servers them selves... the servers are 2 Enterprise & 1 standard 2K3 SP2, they also have Mcafee Antivirus ( file level with Exchange folder exclusion ) and Mcafee GroupShield on them... Curiously all email functions are ok, able to send and receive internally and to Internet, just not able to telnet to port 25 on any servers... If I add another port to the SMTP VS, then able to telnet that port, but not 25, so I think one of the Anti-virus programs is stopping port 25... ...

Publisher 2000 to Publisher 2003
I have been using Publisher 2000 and working fine. I have a webpage and just Save as Webpage and then upload to my server.

Exchange delayed delivery/NDR due to 421+Server+too+busy (greylist bug?)
Exchange 2003 SP2. I think we are seeing the exchange "greylisting" bug where emails sometimes get stuck and are not sent, nor are the users notified in a timely manner. In my case it is not greylisting but a 421+Server+too+busy error that exchange is not retrying on. Most of the time the emails to a particular client get through, it is the occasional one that does not. If I look at the message history in the message tracking cneter it shows "Message transferred to OTHER_MAILSERVER through SMTP" for the successful sends. For the failed sends it shows ""Me...
