2. Check the DNS setting.
How to Check the DNS setting
1. Get the IP address of the DNS server from the customer.
2. Request the customer to check the DNS server.
• How to check the address of the DNS server by the PC (reference).
Check by either of the following methods:
Run "ipconfig / all" at the command prompt on the PC, then check the IP address of the DNS
server.
Open the IPv4 properties screen in the PC, check the IP address setting of the DNS server is
whether manual or automatic.
• If the access to the external server is restricted, request the network administrator (customer) to
permit the following FQDN name for communication.
- FQDN: p-rfu-ds2.support.ricoh.com
3. Ask the customer the prohibited time and day of the week of ARFU execution.
4. Check SP5-816-087 (Remote Service: CERT:Macro Ver) and make sure the encryption
level is 2048 bit.
[1]: 512 bit / [2]: 2048 bit
• If SP5-816-087 is [1]: 512 bit, specify the settings as follows:
1. Initialize the encryption level by executing SP5-870-003 (Common Key Info Writing:
Initialize)
2. Rewrite as 2048 bit in SP5-870-004 (Common Key Info Writing: Writing 2048 bit).
3. Turn off and on the main switch.
• ARFU uses the same certificate as @Remote to communicate with the Global Server. This may
cause failure in connecting with the Center Server, if the device is to be installed in the
following conditions. Make sure to check the conditions before changing the encryption level
and do the corresponding workaround.

external appliance.
