Issues with Ports on Windows Servers

I have come across a number of comments in forums about asking how to determine what software is using a particular port.  This query happens when you are trying to install software which fails due to a port being utilized already.  I came across the same query and remembered that I could do this using NETSTAT but couldn't remember the switches.  Well I found the information and thought I would share:- netstat -aon | findstr Eg: with port 443 If you kill the related process then the port will be become free. Note : Normally PID column will not be visible in…

SQL Server Performance

It is pretty important to make sure you set the Max Server memory setting for SQL Server 2005/2008 to something besides the default setting (which allows SQL Server to use as much memory as it wants, subject to signals from the operating system that it is under memory pressure). This is especially important with larger, busier systems that may be under memory pressure. This setting controls how much memory can be used by the SQL Server Buffer Pool.  If you don’t set an upper limit for this value, other parts of SQL Server, and the operating system can be starved…

When adding a 4.1 ESX/ESXi host to an Active Directory domain it fails or whilst adding you receive an error "Errors in Active Directory operations". If you have netlogond enabled on the host, you can check to see if you have similar entries in the netlogond.log: 20100820075107:0xf7c74b90:DEBUG:[LWNetSrvGetCurrentDomain () /build/mts/release/bora-234910/likewise/esxi- esxi/src/linux/netlogon/server/api/lwnet-pstore.c:83] Error  at /build/mts/release/bora-234910/likewise/esxi- esxi/src/linux/netlogon/server/api/lwnet-pstore.c:83 [code: 136] The issue is more than likely down to TCP/UDP ports not open between the ESX/ESXi host and Active Directory server. Make sure you have the following TCP and UDP ports open:- Required (TCP and UDP) ports are Port 88  - Kerberos authentication Port 123 – NTP Port 135 - RPC Port 137 - NetBIOS Name Service Port…
