Outside users attempting to send emails to our domain were blocked with the following error:
554 5.7.1 This message has been blocked because ASE reports it as spam.
I have extracted this info from Fortinet KB:
The AS Engine feature was released in FortiOS 4.0. A new AntiSpam Rule Set was also introduced in v4.0, this is the new rule which contains a Heuristic Antispam check for all suspicious spam upon passing through a firewall. READ MORE »
Here is a sample showing how to build an Inter-Switch Trunk (IST) between two Nortel/Avaya switches over a Multi-Link Trunking (MLT) for redundancy.
IST is a protocol used to connect two switches together to create a single logical switch for redundancy purposes, using it with MLT and the link itself become redundant
Note: IST is supported on Nortel/Avaya Routing Switch 1600, ERS 5×00, ERS 8×00 and requires a license. READ MORE »
The file system compression can be a major overhead for servers during the backup time and in extreme cases it can double the time it takes to backup the server.
To prevent from accidentally using the compression on your server you can try the steps below to edit Registry and disable compression function. READ MORE »
In my previous post “How to: claim lost space on drive c: under SBS 2008” I have mentioned the obvious things that can be done to free space from drive C: on an SBS 2008 server.
Today I discovered another fast growing and space consuming service, sharepoint…or to be precise,the SharePoint Config database Log file located at C:\Windows\SYSMSI\SSEE\MSSQL.2005\MSSQL\Data\Sharepoint_config_***.ldf
this file can be huge. READ MORE »
I had a problem today with an exchange 2007 RTM server that refused to accept incoming mails.
Testing with telnet to port 25 and trying to send an E-mail manually, produced this error:
452 4.3.1 Insufficient system resources
Just a quick reminder to myself, FortiClient SSL VPN can drop the dialing process if the “Mcafee security scan plus” is installed on the PC.
Check in “add/remove programs” if you see the “Mcafee security scan plus”, uninstall it and try to connect again.
A lot of security software like anti-viruses and personal firewalls can interfere with the dialing process of the SSL VPN, try to disable them if the problems persists.
Update:
Microsoft Security Essentials is blocking the dialing process too.
Update 2:
Try to disable IPV6 from network setting.
I had the “pleasure” to recover a windows 2008 installation today, after a failed try to clone the server to an external disk with acronis.
For some reason the acronis changed something in the source disk boot sector and when the clone finished, the server did not boot and displayed this error:
Missing or corrupt \windows\system32\winload.exe
status: 0xc000000e READ MORE »
I downloaded and tested last week the new FreeNAS version 8, it’s based on FreeBSD 8.0 and I was impressed with the new look, it feels like it made the jump from an experimental software to a mature storage platform with slick interface and well supported history. READ MORE »
If you ever installed an SBS 2008 server you know you need to assign drive C: with a lot of space, the exchange and the WSUS servers are installed by default in drive C: and hold there data in the installed directory.
over time the user mailboxes grows and the exchange database can get really big, not just that, the IIS log directory under c:\inetpub can become huge as the WSUS server writes it’s logs there. READ MORE »
I had an odd problem today with an SQL 2008 server backup to a network share.
The maintenance plan that was scheduled to run daily and backup the databases, were falling with an access dined error to the network location for some reason. READ MORE »
A couple of days ago I had to convert an old windows 2000 server to VMWare using Vmware converter (P2V).
After the conversion, It seemed like the windows 2000 virtual machine consumed a high CPU usage from the ESXi host.
In the vSphere vCenter the virtual CPU indicate 100% CPU usage.
Inside the VM, the Task manager showed a normal cpu usage. READ MORE »
Recently I have upgraded a VCenter to the latest version 4.1 Update 1 and immediately after the upgrade the java.exe*32 process consumed 100% CPU, I figured it is a part of the upgrade process so I waited a few hours to see if the CPU settled down with no joy.
After digging for the answer and checking with VMware support it seems like it’s a well-known bug with the Update Manager. READ MORE »
Eset nod32 has surprised me with its simplicity and lightness.
After working with Symantec for many years and getting used to the thick and resource demanding SEP (Symantec endpoint protection) the nod32 seems to work without bothering the end user and does what it suppose to.
After implementing it on several networks I have realized I cant upgrade the client installed AV when a new version came out without central distribution software like Microsoft SMS or System center configuration manager. READ MORE »
I’ve installed last week a new windows 2008 R2 SP1 x64Bit as a terminal server or as Microsoft calls it now “Remote Desktop Services”.
This server delivers an MS access based application to the users and connects to MS SQL server through ODBC.
The standard way for creating the ODBC connection is system DSN: Control Panel>Administrative Tools>Data Sources (ODBC)>System DSN.
In my case it did not work, the application insisted it has a problem with the ODBC connection to the database and ignored the DSN. READ MORE »
