Error 1232 (The network location cannot be reached)
Sherratt Rowan
I set up POP3 mail on a new SBS 2003 server a couple of days ago, and it
seemed to be working fine. However, I now get three errors in the Event
Viewer, the most informative of which is:
Event Type: Error
Event Source: POP3 Connector
Event Category: Download
Event ID: 1036
Date: 29/05/2006
Time: 10:30:16
User: N/A
Computer: BSERVER
Description:
An error occurred during a POP3 transaction to server <mail.pins.co.uk
[sher...@bslbeam.co.uk]>. The error is 1232 (The network location cannot be
reached. For information about network troubleshooting, see Windows Help.
).
The other two just say the process was ended and finished with errors.
I've tried pinging the mail server address and it seems fine. I can't find
any other information relating to the error number. Does anyone have any
idea what might be causing this?
Thanks

Thank you for posting in SBS newsgroup.
From the description, I understand the issue to be: you got POP3 Connector
1036 in event log. If I have misunderstood your concerns, please do not
hesitate to let me know.
As I know, 1036 is a failure to connect to POP3 server, either due to
authentication failure or network problem. The most possible cause is
related with ISP or router. It also may be caused by the MTU package size
or the EDNS0 DNS resolution.
Please make sure the external POP3 server does work well and the Internet
connection is stable. Also confirm with ISP to see if the service provider
has implemented blocking filter on the POP3 server. The filter will block
the connection if a client connects to the POP3 server every second. As
POP3 connector is designed to have multiple threads to do as many
connections as possible at the same time the POP3 connector will trigger
the filer and block the connection. The POP3 connector is able to connect
successful for the first 10 accounts before the filter blocks the
connection.
I also see the issue being solved by changing the ISP server the POP3
connector is pointing to. You can contact the ISP to see if there is any
other DNS server available. Also, if you have already configured multiple
DNS servers in DNS forwarder tab, you may try to change the query order of
the DNS servers. Will the POP3 connector issue still occur?
We also have identified this issue may occur on Linksys router
BEFVP41/BEFSR41. As I know Linksys has released the KB article KB10934318
and KB10934351 for it. If you have the router before SBS 2003, you could
consult the Linksys support for more information.

If it is not your scenario, would you please help me confirm how you
configure the networking and Internet access for your SBS 2003 server? Did
you follow the steps in the following KB?
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763
On the SBS server, please follow the steps below to see if the network
binding order is configured properly:
1. Right-click My Network Places and then click Properties.
2. On the Advanced menu, click Advanced Settings.
3. Under Connections, use the up and down arrow buttons to put the
connections in the following order:
- Local Area Connection for the internal adapter
- Local Area Connection for the external adapter
- Remote Access Connections
Also please try to turn off EDNS0 functionality on the SBS 2003 server. To
do so, at the command prompt, type:
"dnscmd <SBS 2003 Server Name>/Config /EnableEDnsProbes 0" (without the
quotation marks), and press Enter.
Check if the issue disappears.
Also I provide the following configuration for your reference:
For one Nic, you need to configure on SBS server and client computer as
following:
SBS:
IP: Fixed IP address
Gateway: your Hardware router IP
DNS: SBS NIC IP as the only entry
In the DNS console (dnsmgmt.msc), right click your ServerName and click
properties. In the Forwarders tab, your ISP DNS server IP should be
inputted there.
On the client workstation, please make sure the configuration:
IP: Assigned by DHCP on SBS or your hardware router
Gateway: hardware router
DNS: SBS INTERNAL NIC IP as the only entry
For 2 NICs on SBS:
On SBS server:
External NIC:
IP: assigned by your ISP or your hardware router
Gateway: your ISP or your Hardware router IP
DNS: SBS INTERNAL NIC IP as the only entry
Internal NIC:
IP: Fixed IP
Gateway: None
DNS: SBS INTERNAL NIC IP as the only entry
In the DNS console (dnsmgmt.msc), right click your ServerName and click
properties. In the Forwarders tab, your ISP DNS server IP should be
inputted there.
On workstation inside your SBS local subnet
IP: Assigned by DHCP on SBS
Gateway: SBS internal NIC IP
DNS: SBS INTERNAL NIC IP as the only entry

Subject: RE: 33988703 - Regarding your post [Error 1232 (The network

newsgroup - (Your original post created date: Jul )
Thanks for contacting me.
I've had a rather busy time over the last couple of weeks and hadn't got
to the newsgroup to check for responses.
I just checked, and there do not appear to be any responses - perhaps
there is an expiration date on responses? The problem has resolved
itself (!) but I would be very interested in your response for future
reference.
Would it be possible for you to resubmit the post?
Thanks for your help
