This section explains how to configure Remote Ink client to autodiscover Remote Ink service using an SRV DNS resource record.
You can enable Remote Ink client software to autodiscover Remote Ink service by creating the appropriate SRV record on the network hosting Remote Ink service. Following installation, Remote Ink client will attempt to discover Remote Ink service by looking up an SRV DNS resource record that points to the Remote Ink service.
Important
If an SRV record pointing to the Remote Ink service has not been created on the network hosting Remote Ink service and roaming user profiles are not configured, then users are prompted to enter the Remote Ink service IP/Domain name when they first log on to a computer hosting Remote Ink client (for example, the first time they use Remote Ink client software in that meeting room).
If roaming user profiles are configured users are prompted only once to enter the Remote Ink service IP/Domain name when they first log on to a computer hosting Remote Ink client and are not prompted again.
To enable DNS autodiscovery, you must add the SRV record to any domain from which a user can connect to a hosting of Lync server software.
Example
If a user logs on to a hosting of Lync server software with a user ID such as user1@example.com, then the SRV record must be installed in the example.com domain. If another user can also log on to the same Lync server software with a different user ID such as user2@anotherdomain.com, then to enable this user to autodiscover the Remote Ink service, the SRV record must also be added to the anotherdomain.com domain (or the user is prompted for the server information).
If all Lync server software users have IDs that each feature the same domain name, then the SRV record need be installed only in the domain that the users share.
The following procedures can be used to create an SRV record:
Manually configure the SRV record using the DNS server’s management interface
OR
Use a Microsoft PowerShell script provided under the Remote Ink service installation in the Tools folder.

Note
By default, the ManageSrvRecord.ps1 uses a time to live (TTL) value of 86400 (24 hours). This means that any DNS service that queries this SRV record caches the record for 24 hours. This includes the DNS component that runs on every desktop computer. If you’re planning to move Remote Ink service to a different computer and are using a non-zero TTL for the SRV record, the SRV record must be removed 48 hours before Remote Ink service is moved. The SRV record must then be replaced by a record with a 0 TTL value as part of the command used to add an SRV record. This procedure gives each Remote Ink client application time to clear its DNS cache. Alternatively, if you use a TTL of 0 you don’t have to complete these actions.
If a new 0 TTL value isn’t used for the SRV record, computers hosting Remote Ink client that still have the old invalid SRV record in cache don’t see the computer hosting Remote Ink service in its new location (see Checking whether a computer can see an SRV record for information on determining which SRV record a computer sees). A computer’s DNS cache can be cleared manually using the ipconfig /flushdns command.
