You can enable Response Rate Limiting (RRL) on your DNS servers to prevent malicious systems from using your DNS servers to initiate a Distributed Denial of Service (DDoS) attack on a DNS client. RRL prevents your DNS server from responding to too many requests at once, which protects it ...
That would be extremely helpful, let me know if you want to discuss any of the other fixes we've tried before you try them in your environment. By the way, we've since upgraded to Server 2016 across the board and installed an ADFS WAP in front of our primary ADFS server. That was ...
The idea of segmenting your data collection servers into X number of databases (on the same server) is for increased performance and easier administration. Large databases are difficult to administer as they have long backup times, long DBCC times, and long index rebuild times. If you can split...

This group excludes the Guest account and the Anonymous User from IIS. The Authenticated Users group can be composed of authenticated security principals from any trusted domain, not just the current domain. You can make use of this knowledge and these groups if setting up the corresponding COM...
And, of course, there's also the option of not using load balancing on a cluster. In some scenarios—for example, a small testing and staging environment—you can disable load balancing because it really isn't needed. There are also times during synchronization and monitoring when it's ...
tools like the COM/OLE browser that ships as part of Visual Studio 6 can be a godsend. This GUI tool will allow you to explore all of the interfaces exposed by arbitrary components, including all of the signatures for the methods exposed by these interfaces. Naturally, the names of the in...
You should plan your SACL implementation, and you should test your SACLs in a realistic lab environment before deploying them to a production environment. This approach prevents overload of the security logs from too much data. Local Policies/ Audit Policy Audit Logon Events Enable audit success...
In many scenarios, you may have deadlock symptoms, but no error. For example, the server may hang and not respond. If this is the case, follow normal troubleshooting procedures first. For example, ask what else is not working. Is the request blocked in IIS or is it blocked because of ...
