Export DHCP db

Windows To export your DHCP db for import into SQL or some other db for analysis, use the NT4 Server Resource Kit utility dhcpcmd. The syntax is: dhcpcmd  scope_address  enumclients [-v | -h] where -v is verbose and -h generates hardware information If you need to move the dhcp server db from on server to another, see  How to Move a DHCP Database to Another Windows NT Server  . That is the Microsoft way. A very conservative approach is to recreate the scopes on a new server and let them be deactivated: Use DHCPCMD to import the IP-reservations in the scopes (if there are no reservations, you don't have to do the import of course). Then, deactivate a scope from the old server and activate the corresponding scope on the new server. This should work perfectly as the clients send broadcasts to look for a DHCP server. In the clients' event logs, you'll see NACK errors from the old server. Don't worry about those, a client always checks for the last known DHCP server fi

Enable DHCP Logging

DHCP Service logs startup and shutdown events in the Event Viewer. You can enable detailed monitoring logs: Right-click the DHCP server in the DHCP Administration Tool Click Properties On the General tab, click Enable DHCP Audit Logging This will create a log file winnt\system32\dhcp\DhcpSrvLog.xxx.

STEP BY STEP solution Note: These are the exact steps for Win 7. I think is the same on Win 8. To get the actual amount of PageFile usage, start 'Performance Monitor' (perfmon.exe), and 'Add Counters' -> 'Paging File' -> 'Usage'. It will give you the answer in %, but you know the total amount of paging file so you can calculate the exact amount of USED paging file (in MB). To read the total amount of paging file: Press Win+Break to open 'System properties'. Go to: 'Advanced' -> 'Performance' -> 'Advanced' -> 'Virtual memory' -> 'Total paging file size' (in MB) ).

Windows 2008 R2 Memory Counters in Task Manager Posted on   May 2, 2011   by   Rickard Nobel How to use  Task Manager  in Windows Server 2008 R2 and Windows 7 to interpret actual memory usage. The easiest and fastest way to check CPU and Memory usage of a Windows Server is often to use Task Manager, however the data given in the tool is not so obvious as it may look. Task Manager is an old tool that has been available since at least Windows NT 3.51 and has been somewhat modified in each Windows Server release since, however rarely completely understood. (The best way to start Task Manager is the press  CTRL SHIFT ESCAPE  at the same time. This may seem stupid, but they are all located on left side of the keyboard and can be touched together with one hand.) In a series of posts I will discuss how to read and understand the memory output of Task Manager in the most common Windows operating systems. Unfortunately many of the values have very different names and meaning betwee

Explanation of Pagefile Usage as reported in the Task Manager TechNet Archive   8 Jan 2008 11:18 AM  7 In this post i am trying to explain the usage of page file as reported in the task manager. Many of us beleive that the page file usage shown in the task manager is the actual usage but this is not so. The below explanation will clarify it. PF Usage as reported in task manager in Windows XP and Windows Server 2003 is actually the system commit total. This number represents potential page file usage, not actual page file usage. It is how much page file space would be used if all the private committed virtual memory in the system had to be paged out all at once. The task manager ;what it calls “pagefile usage” is actually the system commit charge (the total number of committed pages in the system). It can grow as high as the current commit limit, which is roughly the sum of all pagefiles and RAM . Page  file usage is  ,the amount of Committed Bytes – I.e. the amou

Using DNS Aging and Scavenging

https://technet.microsoft.com/en-us/library/cc771677.aspx https://technet.microsoft.com/en-us/library/cc757041(WS.10).aspx
Symptom Some DNS records may be deleted from DNS server automatically. For example, you have created static A records for your printers.    However, these records are deleted automatically. Cause This problem may occur when DNS scavenging is enabled. DNS scavenging is feature which helps remove stale resource records automatically. Scavenging improves DNS server and zone transfer performance when working with dynamic update together. However, some devices may not be able to perform dynamic update. When DNS scavenging is enabled, these records may be recognized as stale and deleted automatically because they are not updated timely. Solution Scavenging is set in three places on a Windows Server: 1.                     On the individual resource record to be scavenged. 2.                     On a zone to be scavenged. 3.                     At one or more servers performing scavenging. It must be set in all three places or nothing happens. You may confi
