A Concurrent Use License allows a user access to any licenses available through the Central License Manager servers, maintained by DoIT, through the Statewide Government Intranet (SwGI).
Concurrent Use licenses are available to Maryland State agencies and their contractors for ArcGIS Pro, ArcGIS Desktop and Desktop extensions products.
Concurrent Use License Request
Concurrent Use licenses are requested directly from the Central License Manager servers. Each agency's firewall must allow traffic to and from the Central License Manager servers in order to access Concurrent Use licenses. Check with your IT Support Unit to determine if the firewall ports have been configured to allow outbound and inbound communication with the following IP addresses:
| Primary Server: |
27000 & 27001 for 10.202.60.10 (gislm1.doit.net.md.gov) |
| Backup Server: |
27000 & 27001 for 10.10.9.8 (gislm2.doit.net.md.gov) |
Note: If agency staff have the capability of establishing a VPN from remote sites to the agency network than changes to the firewall may need to include allowing traffic to and from where the user VPN terminates.

All Esri software product(s) require a software license file. For concurrent use products, each product accesses licenses from the Central License Manager server. Step-by-step instructions walk users through the process to connect to the Central License Manager and access the concurrent use license files. Instructions assume the software has already been installed. For information on software installation, go to the Software Overview page.
Eligible users also have the option to "check out" concurrent use licenses for 30 days of disconnected accessibility. The Concurrent Use License Authorization instructions also include step-by-step instructions on how to perform a check out.
