DNS _ WINS DIFFERENCE

-
WINS DNS
WINS maps NetBIOS names to IP Addresses DNS maps Hostnames to IP Addresses
To find the netBIOS names your PC
has registered type "nbtstat -n" at a command prompt and press enter		 To identify your computers Hostname type "hostname"
at a command prompt and press enter 
NetBIOS name is a 16 byte address Hostnames can be up to 255 charachters in length
WINS was always used by organisations for name resolution on their local network
NetBIOS names are located through a series of steps that begins
 with checking the local cach
 LMHosts file HOST FILE
WINS is platform dependent DNS is platform independent
WINS supports dynamic IP addresses DNS supports static IP addresses
WINS supports incremental reproduction of the data for any modifications DNS copies the entire database.
WINS does not support TCP/IP application services DNS supports all TCP/IP application services
What is the DNS cache?
When you type a web address into your web browser and press Enter, you're sending a query to a DNS server. If the query is successful, the website you want opens; if not, you'll see an error message. A record of these successful and unsuccessful queries is stored in a temporary storage location on your computer called the DNS cache. DNS always checks the cache before querying any DNS server, and if a record is found that matches the query, DNS uses that record instead of querying the server. This makes queries faster and decreases network and Internet traffic.
dnsmgmt.msc Set-DnsServerRecursion -Enable 0
ipconfig /flushdns
net stop dnscache dnscmd <Server name> /Config /NoRecursion 1
ipconfig /registerdns
What is scavenging? Finding and deleting unwanted records.
What is the main purpose of SRV records ? 
SRV records are used in locating hosts that provide certain network services.
If you wish to stop XP from placing negative entries into cache, you can make this change in your registry.
1. Goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Dnscache\Parameters 
2. Build a new DWORD value called NegativeCacheTime and give it a value of 0

Quick Reference: Troubleshooting Netlogon Error Codes ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ January 28, 2013   by  Mark Morowczynski [MSFT]   //   24 Comments 0 0 Hi this is Brandon Wilson and today I will be providing you with a quick reference for troubleshooting Netlogon error codes. I say “quick reference” very loosely here, because this is one of those sticky subjects that can easily expand into many more areas and become a very long discussion. So, I’m going to do my best to focus on just the codes and possible solutions for the error codes that are more common to see. Anyone who has dealt with some of these issues knows that some of these outlined areas can lead to huge revenue loss for a business, or at the very least an annoying authentication prompt J I welcome you to leave comments and questions, or suggestions for articles that you as the reader would be interested in seeing us do on AskPFE Platforms ( http://blogs.tech...
