To modernize and better secure the mainframe environment, an update has been configured to the Annapolis Data Center - Host access in the cloud (HAC) web client (ADC Web Mainframe Session). Going forward, you will now need to authenticate using your Maryland.gov credentials.
On June 20th, the legacy ADC Mainframe environment will NO longer be available, and you will be required to utilize the new environment with the updated link. Please follow the one-time registration steps outlined in the HAC instructions below.
