IPSEC service fails to start

I found on several of our servers that the ipsec service fail’s to start on some of our SBS servers, this is because the DNS service randomly picks 2500 ports and seems to pick the port ipsec uses, to fix this you need to add some exclusions into the registry.

Open regedit and go to  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ReservedPorts and type the following numbers in addition to the ones already there.

  • 1645-1646 – Used by IAS
  • 1701-1701 – Used by L2TP
  • 1812-1813 – Used by IAS
  • 2883-2883 – Used by AUTD
  • 4500-4500 – Used by IPSEC

I found this info on the Official SBS Blog

Internet Explorer was not able to open this internet site downloading a document from secure website

When attempting to download a pdf file from a secure website in our case the wonderful people at HMRC we received the error message Internet Explorer was not able to open this internet site. The requested site is either unavailable or cannot be found. Please try again.

To cut a very long story short it turned out to be a tick box within internet explorer.

SOLUTION:
Internet Explorer-> Tools menu-> Internet Options-> Advanced tab
Go to the Security section all the way at the bottom.
Tick  “Do not save encrypted pages to disk”
Close all Internet Explorer windows
Start IE and download the file again

Access denied when tring to access mapped drives and join a domain

One day when trying to access a mapped drive i received an “access denied” if i tried to access the server directly using the share name it prompted for a username and password and even though the details are correct the box keeps coming back.

So i dis-joined it from the domain and attempted to rejoin it again but again got the access denied error message, after some searching it turned out to be SMB signing was turned off on the client machine, to re-enable i needed to go to the following registry keys

HKLM\system\current control set\services\lanmanserver\parameters
HKLM\system\current control set\services\lanmanworkstation\parameters

Requiresecuitysignature change to 1
Enablesecuritysignature change to 1

and after a reboot all was well again.

Sage Line 50 username already in use

If you receive username already in use or too many users logged in when trying to go into sage it usually happens if the program crashes or the machine was shut down without logging out properly.

To clear the user go to where ever the sage data is stored in our case it was on a server w:\company.001 and delete the queue.dta file.

No pixels more than 50% selected?

Tonight I was working with Photoshop trying to make a selection with the lasso tool, when i had made the selection i got the message pop up “No pixels more than 50% selected. Edges of selection will not be visible”

After a bit of digging this turned out to be the feather was too big for the size of the selection, why they couldn’t have made the error message say that I don’t know.

Change the MTU under Vista or Windows 7

First of all you are going to need to find the optimum mtu for your situation to do so follow these instructions.

ping www.google.com -f -l 1500 (lower case F and L not a 1)

you will receive something similar to this.

Pinging www.l.google.com [66.102.9.105] with 1500 bytes of data:
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.

Ping statistics for 66.102.9.105:
Packets:Sent = 4,Received = 0,Lost = 4 (100% loss),

Now you need to drop the packet size down by 10 bytes until you find one that doesn’t fragment in this case it was dead on 1430 but you can increase the byte size by small factors eg 1431,1432 etc until you find that largest possible packet for your situation.

Ping statistics for 66.102.9.103:
Packets:Sent = 4,Received = 4,Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 64ms,Maximum = 100ms,Average = 74ms

Now you need to add 28 to the maximum size for the overhead the IP headser and the ICMP Echo Request, so I end up with 1430+28=1458 then you need to change the MTU to do so.

1. start an elevated cmd prompt
2. type netsh interface ipv4 show subinterfaces (this will show you the existing mtu and network adptor name)
3. type netsh interface ipv4 set subinterface “Local Area Connection” mtu=1458 store=persistent

Excel 2003 slow opening files on a network

Today i came across excel files opening slowly when you search for this problem there appear to be many people having similar issues, to cut a long story short it turned out to be the Office File Validation tool that had come down with the windows updates.

Method 4 solved the issue for me on the Microsoft website

Manually Delete a Windows Service

To delete a service manually first of all you need to find the service name go to Administrative Tools and then Services and double click on the service you want to remove, take a note of where it says service name

I this example its AcrSchSvc then you need to open an elevated command prompt and type sc delete (Service name)

eg. sc delete AcrSchSvc

Keep losing the gateway on SBS 2008

I noticed recently when one of our sbs 2008 servers got rebooted the gateway would disappear, the first time it happened i thought nothing of it I just ran the fix my network wizard and that sorted it but the next time it rebooted it disappeared again, it turns out its a known issue i found the answer on the SBS Blog

1. To fix the issue go to the TCP/IP properties of the network card and enter in the proper default gateway.

2. Download the hotfix and install to stop it happening again

3. Manually edit the registry to remove the extra spaces in the following location HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Para
meters\Interfaces\<GUID>\DefaultGateway

The guid is the interface for the network card if you have one there will be one entry if you have two network cards there will be two entries.

3. Double click the value for DefaultGateway and remove the blank lines above and below the gateway address and click ok.

4. Reboot server if needed.
