5. Access Edge Certificate Names

The required names for an Access Edge Server certificate are as described here:

Subject Name—Ensure that the subject name matches the Access Edge FQDN entered in the Topology Builder.

Subject Alternative Names—The SAN field must contain all supported SIP domains in the sip.<SIP Domain> format.

6. Web Conferencing Edge Certificate Names

The required name for a Web Conferencing Edge Server certificate is as detailed here:

Subject Name—Ensure that the subject name matches the Web Conferencing Edge FQDN entered in the Topology Builder.

7. A/V Authentication Certificate Names

The media relay certificate does not have any specific name requirements.

8. Wildcard Certificates

Some organizations attempt to use wildcard certificates or a single certificate with subject alternative names that attempt to cover all possible names. There are certainly some cases in which this configuration might work, but in the end the simplicity of following the actual name requirements tends to outweigh any small cost savings achieved by using fewer certificates. If you are attempting one of these configurations and experiencing issues, use the correct names to see whether that resolves the issue.

9. DNS Records

Successful sign-in to an Edge Server is heavily dependent on correctly configuring the DNS.

• The NSLookup tool can be used to verify that the necessary DNS records .


Tip

When troubleshooting any Edge Server issue, it is important to check that all necessary DNS records exist and are resolving to the correct IP addresses.


The following sample NSLookup sequence within a command prompt checks the host record of the pool:

nslookup
set type=a
lyncedgepool1.companyabc.com

A successful query returns a name and an IP address. Verify that the IP returned matches the IP addresses assigned to the Edge Servers or load balancer and that no extra, or surprise, IP addresses are returned.

To verify the SRV record required for automatic client sign-in externally, the syntax is slightly different. The following is another sample NSLookup sequence:

nslookup
set type=srv
_sip._tls.companyabc.com

A successful query returns a priority, weight, port, and server hostname. Verify that the server name matches the Edge pool Access Edge FQDN and that the correct port is returned.

Use the same steps to verify that the following services resolve correctly in public DNS:

• Access Edge FQDN

• Web Conferencing Edge FQDN

• A/V Edge FQDN

For internal DNS, verify that clients can resolve the following:

• Internal Edge pool FQDN


Tip

Ensure that the Edge Server can resolve internal DNS names of all Lync Servers. It must be able to properly resolve these DNS entries to communicate with internal servers and users.
