Problem

Event ID 12014

Microsoft Exchange could not find a certificate that contains the domain name {name.domain.com} in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector SendConnector with a FQDN parameter of {name.domain.com}. If the connector’s FQDN is not specified, the computer’s FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.

In the error massage take note of {name.domain.com} this name is being used on one of your mail connectors, and the certificate on the Exchange server has a different name.

Solution

1. Launch Exchange Management Console > Organization Configuration > Hub Transport > Send Connectors > Right click your Send connector > Properties > Make sure the “Specify the FQDN this connector will provide…” section is the same as the name on your servers certificate.

2. Launch Exchange Management Console > Server Configuration > Hub Transport > Receive Connectors > Right click your Send connector > Properties > Make sure the “Specify the FQDN this connector will provide…” section is the same as the name on your servers certificate.

3. Start > run > services.msc {enter} > Restart the Microsoft Exchange Active Directory Topology Service > Select “Yes” to restart the other services.

IP Address Conflicts with VMware ESX and Cisco ASA

Posted on by

KB ID 0000635

Problem

My colleague was setting up a DMZ server for one of our clients, it was a virtual server that was presented to the DMZ of a Cisco ASA 5510. Every time he gave it a static IP address it popped up an IP address conflict (no matter what the IP address was).

Windows has detected an IP address conflict
Another computer on this network has the same IP address as this computer. Contact your network administrator for help resolving this issue. More details are available in the Windows event log.

He asked me to set up DHCP for the DMZ to see if that would cure the problem, which I did. However that also refused to work either.

Windows IP Configuration
An error occurred while renewing interface Local Area Connection : The DHCP client has obtained an IP address that is already in use on the network. The local interface will be disabled until the DHCP client can obtain a new address.
An error occurred while releasing interface. Loopback Pseudo-Interface 1 : The system cannot find the file specified.

Solution

Turns out this is a known problem, and is pretty easy to rectify.

Option 1 (On the ASA)

1. Connect to the ASA via command line, log in and then go to enable mode

[box]

Password:******
Type help or '?' for a list of available commands.
PetesASA> enable
Password: ********

[/box]

2. Enter configure terminal mode then disable proxy ARP on the interface that’s presented to the problem network, (in this case the interface is called DMZ).

[box]

PetesASA# configure terminal
PetesASA(config)# sysopt noproxyarp DMZ

[/box]

3. Save the changes.

[box]

PetesASA# >write mem
Building configuration...
Cryptochecksum: 79745c0a 509726e5 b2c66028 021fdc7d

7424 bytes copied in 1.710 secs (7424 bytes/sec)
[OK]
PetesASA#

[/box] Note: You can also disable proxy arp in the nat tranlation, with the no-proxy-arp like so; [box] PetesASA(config)# nat (inside,DMZ) source static Inside-LAN Inside-LAN destination static Inside-LAN Inside-LAN no-proxy-arp [/box]

Option 2 (On the affected machine)

Note: This is is for Windows based clients. 1. Start > Run > regedit {Enter}. 2. Navigate to;

[box]

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters

[/box]

3. Create a new DWORD value called ‘ArpRetryCount’ and set its value to 0 (Zero).

4. Reboot.
