If you use "dial-up" to connect to an Internet Service Provider (ISP), you must use the NASA HQ Dial-in service to connect to the NASA HQ Domain Name Servers (DNS) which are behind the NASA HQ firewall.
To obtain the phone numbers for HQ dial-in service, call the IT Help Desk at 358-HELP (4357) or 1-866-4NASAHQ (462‑7247). Once connected to the HQ network, you will be able to access e-mail and Internet services. Should you encounter problems or need assistance, contact the IT Help Desk.
