When Domino HTTP Server started, it report this error even no process is listening port 80. Actually it is caused by Trendmicro

HTTP Server: Error - Unable to Bind port 80, port may be in use or user needs net_privaddr privilege 

1. Open the Registry Editor on the domino server.
2. Important: Always back up the whole registry before making any modifications.
3. Navigate to HKLM\SOFTWARE\TrendMicro\NSC\TmProxy\WhiteList
4. Click Edit > New > Key and then name the key "Domino".
5. Under this new key, create a string value (Edit > New > String Value) named "ProcessImageName". Set the value to "nhttp.exe".

HRSP ARP Issue

Recently, I help my sibling company to setup HSRP configuration

1 Cisco 2921 connecting 2 Cisco 3650.

It works normally without any problem at the very beginning.

Later, user reports that Windows 2008 report duplicate IP after rebooting or re-enable network adapter.

After a serious a research, I got the following findings.
1. ping to unused ip address will got TTL expire.
2. traceroute to unused ip address will loop between that 3 Cisco device.
3. all unused ip address in Cisco 3650 arp table will map to ether-channel mac address.

After digging a 2 weeks about this problem, finally I found an article on the web. It said Cisco has made some changes on IOS after 12.8 which I need to add "no ip proxy-arp" on both 3650 uplink to 2921.

Fix "RRV bucket is corrupt" on Domino CA Process

Today I have met a problem during submit a request to CA process on my domino server.

It prompt out "RRV bucket is corrupt" after choosing CA server and press OK.

I tried all method like fixup, updall, compact, restore from backup....no luck.

Finally, I open Address book-> Security-> Certificate-> <<My CA Server NAME>> and press Edit Certifier

There is a CFG???????????????.nsf  attachment inside. I try to open it, it prompt the same error.

So I think it is worth to try so I delete that attachment and Save.

It fixed the problem!
