  • 1. DNS Out of Sync
    I'm running SBS 2003 Premium w/SP1. I've noticed that DNS and DHCP are out of sync on the IP addresses of the internal clients, which are all XP Pro SP2 boxes. Basically, the IP address (Host A records) in DNS are not getting updated by the new IP address leases that are issued by DHCP. My DHCP server has the standard SBS settings that were created by the ICWizard about a year back. The leases do expire in 8 days and I have checked the option to automatically update DNS when the leased IP address changes. In DNS, the forward and reverse records are different for some PCs. While I know that I can manually remove these incorrect reverse records and create new, accurate records, I'd prefer to find an easier method becasue I do have about 65 PCs. I have rebooted the SBS box and ran ipconfig /flushdns with restarts of netlogon as an attempt to remove the bad records. As a side note, DHCP and DNS have been running fine for about a year. I noticed this issue about a week back while rolling out new Dell PCs. I do use a Windows image along with sysprep. I know the sids are getting updated because WSUS is working. But on the PCs that I replace, I am giving them the same name as the old PC that is removed from the floor and network. Thanks for the help. Ken
  • 2. Low on Virual Memory in SBS 2003
    A client with SBS 2003 is receiving the message below on the server display. They have 3 Gb of RAM. The server was installed about 6 months ago. Although the SQL Server has been running since the first day, we only actually started putting transactions thru about a month ago. According to the client, the error message below seems to occur over the weekend as it is on the server display on Monday morning. The SQL server logs seem to be clean and I am not sure what to look for in the Event Viewers (or anywhere else). Thank you in advance. The message is:" "Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied. For more information, see Help." -- Regards, Allan C
  • 3. Installing SBS2003 in place of Server 2000
    As soon as it arrives,we are going to install a new SBS2003 server in place of a Win2000 server. The way we intend to do this is to completely disconnect the old server from the network, then install the new server After that, we want to copy all the data files from the old server over to the SBS2003 server, and use the Win 2000 server box strictly for data files backup. Since I haven't connected a second server to a network before, are there any issues I need to watch for? Thanks. Leon
  • 4. Which ports are open?
    Is there a way - from the SBS2003 - to tell which ports are open? Especially those ports affecting email in and out, remote access, and remote administration? Thanks. Leon
  • 5. 2 SBS on same network.
    I have a client with one SBS 2003. Another company is going to be moving in with the 1st client at the end of this month and they will be bringing their SBS 2003. I am aware 2 SBS cannot belong on the same network, however, I have read that they can co-exist on the same net so long as they are on separate domains. I know I will have to work out the IP numbers and such, and also have to turn off one of the DHCP servers. What I am concerned a about is DNS. The companies would definitely benefit being on the same network so they can both take advantage of the high dollar printer/copiers. Should I be concerned about anything? especailly DNS. Thanks

#5.1.0 smtp;550 5.1.0 Authentication required

Postby Sm9lbCBC » Sat, 03 Nov 2007 23:10:00 GMT

I'm a novice MCSE. On the side I'm supporting a small network (SBS - 3 
workstations - Exchange).  The small network was built nicely by a networking 
company who became too expensive for my client, who is a friend, who asked me 
to support it.

The first Thing (and only thing) I've done was changed the Administrator 
Password on the server.

Now I've had reports of this error when users try to reply to emails.

 The e-mail address could not be found. Perhaps the recipient moved to a 
different e-mail organization, or there was a mistake in the address. Check 
the address and try again.
  <mydomain.com #5.1.0 smtp;550 5.1.0 Authentication required



They can email successfully if they type out the email address, but it will 
not work when they simply hit reply and send.

Does anyone know what I can try to do to fix this?

Thanks

Joel B

Do you have a PTR record for that domain?

If not Contact their ISP and have them create a PTR record of 
mail.domain.com for them

ello Joel,

Thank you for posting here and also thanks to Russ for input.

From your post, I understand that when users try to reply emails, error 550
5.1.0 is received.

If I have misunderstood your concern, please feel free to correct me.

This issue can be caused by several factors. Let's try following steps to
see if it helps:

Suggestion 1: Re-running CEICW on SBS server:
=============================
Let's re-run CEICW to reset the network configuration. Please refer to
following article to do this.

How to configure Internet access in Windows Small Business Server 2003
http://support.microsoft.com/kb/825763/en-us

Suggestion 2: Prepare a Clean Boot environment.
=================
1. Click Start and Click Run, and in the "Open" line, type in "MSCONFIG"
(without the quotation marks) and click OK.
2. Under the Service tab, check "Hide All Microsoft Services", and then
click "Disable All" button. In this way, we can disable all the services
which belong to third-party programs.
3. Under the Startup tab, click "Disable All" button.

4. Click OK.
5. Choose Yes to restart the computer.
6. Check "Don't show this message or launch the system configuration
utility when Windows starts".
7. Please check if the issue persists.

NOTE: We can check on Normal Startup in the General tab to roll back to
Normal Mode after we get this issue resolved.

If the issue persists, I would suggest you to check the following
information.

1. Does the issue happen for all the email domains or only for certain
email domain? If only for certain email domain, please let me know the
accurate problematic email domain name. You may send an email to
XXXX@XXXXX.COM to let me know.

2. Please save the NDR message as a msg file and send it to
XXXX@XXXXX.COM as an attachment.

3. Please let me know if your internal mail works fine.

4. How does the Exchange server work? Via smarthost or DNS?

5. Please send me an Exchange MPS report

a. Visit
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_Exchange.EXE to download the file.
b. Run the MPSRPT_Exchange.EXE on the server box.
c. Wait for 10~15 minutes.
d. Open Windows explorer, navigate to %SYSTEMROOT%\MPSReports\Exchange\cab\
e. Send the .cab file directly to me XXXX@XXXXX.COM

6. Please enable SMTP log. When the issue occurs again, send me the log:

NOTE: Please let me know the recipient's email address and the sender's
email address.

a. Open Exchange System Manager. Navigate to
Servers\ServerName\Protocols\SMTP\Default SMTP virtual server. Right-click
it and choose 'Properties'.

b. In General tab, check 'Enable logging' option. Click 'Properties'
button, enable *ALL* logging options in 'Advanced' tab.

c. Click 'OK' to close the dialog box. Restart the SMTP virtual server.

d. Reproduce the problem (send e-mail through external account). Wait for
10~20 minutes.

e. Go back to the server. Open Windows Explorer and navigate to
%systemroot%\system32\logfiles\smtpsvc1\ Gather the log file and send it to
me.

If you have any questions or concerns related to this issue, please let me
know.

hanks for the suggestions. I did so many things, that I'm not sure what it
was that fixed it, but I performed the CEICW for the 20th time, and this time
removed the smarthose smptp.comcast.com in the SMTP connector, and I also
updated the secure communication certificate in the SMTP protocal properties.
I tried so many things for so many hours, I'm not sure what did it, but I
believe it was the certificate since I had tried all of the other things
previously to no avail. The above were the last three things I did and It is
now working. BE AWARE of changing the admin password, because that was all I
did to start this problem, and changing it back did not fix it! I want to
believe that the certificate is the key to this, but I really don't know
these things. I hope this helps someone someday.

ello Joel,

Thank you for your reply.

After reviewing your post, I understand that after re-running CEICW, the
issue was resolved.

For this issue, the certificate seems to be the root cause.

If similar issue is encountered in the future, I suggest resetting all the
settings when running CEICW. Sometimes it can save much time and effort.

Thank you for sharing your experience.

4.SMTP communication problem smtp;550 - emails bouncing back

Recently my customer has had emails bouncing back with the error:
There was a SMTP communication problem with the recipient's email server. 
Please contact your system administrator.
<Customer.com #5.5.0 smtp;550-(Customer.com) [1.2.3.4] is currently not 
permitted to relay through>

I do not have a MX record pointing at the Exchange server on the SBS2003R2.
I do not have a smart host setup at this time.
We do have a static IP on the router for the outside and I do have access to 
our dns records at our host.
What would be the proper way to deal with this issue?
Should I do something with MX record and dns?  If so how?
or
Should I setup a smart host to relay from the ISP (Verizon)?

Below is information about our system and information from some of the 
bounced emails.   Names and IP's were changed to protect the innocent.
Any help or advice would be appreciated.
