Error message “Someone is currently logged into the APC Management Web Server. Please try again later”

When you attempt to access your APC Environmental Monitoring Appliance via a web interface you receive the error "Someone is currently logged into the APC Management Web Server. Please try again later"

After confirming that no one is actually logged in it looks as though the web interface has got stuck. If near you could physically power cycle the unit to refresh the web interface. If the appliance is located some distance away the workaround is to telnet to it and then log off by selecting option 4 in the Control Console

Try accessing the web interface now and you should be able to log in as normal.

How to install SQL Server 2008 R2 Client Tools

If you want to install just SQL Server Management Studio and/or the SQL Shared Features such as Business Intelligence Development Studio, Integration Services etc then you will need to run the setup executable from the original SQL media.

Select ‘New SQL Server stand-alone installation or add features to an existing installation’ and accept the default settings to the next few screens. When you get to the ‘Feature Selection’ options completely deselect the ‘Instance Features’ (Database Engine Services/Analysis Services/Reporting Services) instead ticking the relevant ‘Shared Features’.

Continue with the installation and once complete the tools and shared features should be available in All Programs\MS SQL Server 2008 R2

Error ‘DBNETLIBConnectionOpen (Connect()).SQL Server does not exist or access denied’ with SQL Server 2008

I received this error following a SQL Instance upgrade from MSDE to SQL Server 2008 R2 Express and tried to connect to the SQL Instance remotely via a third party application.

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied

Fortunately the solution was simple:

Start the SQL Server Browser service and if required change the Startup Type from Disabled to Automatic

I looked up why the SQL Server Browser service is now disabled by default and the reason is simply that it’s a security best practice to disable the service.

Error importing a Google calendar ‘Failed to import events: Could not upload your events because you do not have sufficient access on the target calendar..’

Whilst I was importing my last calendar into my main Google calendar I received this error despite being the owner of both calendars!

A quick search showed that I’m not the only one to have faced this issue. The resolution that worked for me was to open your exported .ics calendar file in a text editor such as Notepad (best to take a back up copy first) and select Edit > Replace

In the Find what: field select UID: and in the Replace with: field type UID:X (basically it can be X or replace X with any alpha-numeric character (a-z,0-9)

Save the .ics file and redo the calendar import. Now it should import without error.

How to merge Google calendars

I have a number of calendars that I used to share out and I cannot get my Windows 8 phone to display the daily entries from these calendars, only my main google calendar. As a way around this, and as the entries are static i.e. recurring birthdays, I thought I would merge these calendars into my main calendar.

Open your Google calendar and select the drop down arrow for the calendar that you wish to import. Select Calendar Settings

Locate the Private Address: field and right click on the ICAL button and select ‘Save link as…’ This will enable us to take a copy of the whole calendar that you wish to merge

Select a location to save to and choose a name of the iCalendar file and click Save

Select Back to Calendar at either the lower or top right of the screen. Select the drop down next to Other Calendars then select Import Calendar

Select the Choose File button and locate the iCalendar file that you saved earlier. Then select the actual calendar that you want to import your other calendar into. Click Import

Once imported the Import Calendar will confirm whether the import was successful. Click Close

You can now confirm whether they calendars have merged – you should see double entries. Once you’re happy you can either:

– Select the drop down next to the calendar and choose to Hide this calendar from the list or
– Select the Calendar Settings of the calendar that you have merged from and in the Delete Calendar settingselect Permanently delete this calendar

‘The volume you have selected may not be extended’ error when attempting a volume extension using Diskpart

I encountered this problem trying to resize the system drive of a virtual machine. Normally I add the extra space using the vSphere client then power down the VM before adding the virtual disk as a secondary disk on another Windows 2003 VM. There I can usually run Diskpart and safely extend it, detach as a secondary drive and power up the original VM with it’s now extended system drive.

In this instance I received the error:
The volume you have selected may not be extended.
Please select another volume and try again.

After a liitle research and reading I found this which pointed me in the right direction:

I downloaded fsextend and saved into C:WindowsSystem32 and then whilst still using the Diskpart utility, ran the command:
extend filesystem

But I still received the error. I was about to run the fsextend utility directly as the only syntax it requires is fsextend (drive letter) when I realised that I would need a drive letter for the volume I was attempting to extend (I don’t normally assign a letter – the volume usually extends without)

I assigned a drive letter and whilst still in the same session of Diskpart ran extend filesystem again but this time it was successful..

I’m not sure whether simply assigning a drive letter resolved the issue or whether fsextend helped in some way.

I later found out that from Windows 2003 SP2 the Diskpart utility has the extra and originally undocumented filesystem command included natively within the utility. In theory you should not need the fsextend utility above if running the latest Windows 2003 SP2 and it may be worth assigning a drive letter temporarily to see if this resolves the extending issue in the first instance.

How to correctly rename a default instance of SQL Server 2005

After we did a migration from an earlier version of SQL to a new server we needed to rename the Windows server to match the old one.

It does actually seem to rename the SQL instance when you open SQL SSME but there is an extra step to complete fully:

Run the following in Query Analyser:


Which will return the old name of your SQL Server

Then using the quotes if needed (esp if your server name includes a hyphen) :

sp_dropserver ‘old server name’
sp_addserver ‘new server name’, ‘local’

Run SELECT @@SERVERNAME again should return the name of the correct server

How to set the Access 2003 Security Level to Low for all user profiles

By default the Security Level in Access 2003 is set to Medium (Tools > Macro > Security). If a database has macros built in then you will be prompted with a couple of messages regarding ‘blocking unsafe exceptions’ and ‘do you want to continue to open.’

My particular issue was with an Access 2003 database that was to be accessed by a large number of users via a Terminal Server.

To suppress these messages you need to set the security level to ‘low’. Although you can do this in Access itself, this only applies to that user profile.

To set across all user profiles you need to add the following registry key (obviously take a backup of the registry before making any changes)

I had to create the Security key as it didn’t already exist.


Error ‘The Logon User Interface DLL NWGINA.DLL failed to load’ instead of a login prompt

I had removed the Novell Netware client from an XP workstation and received this error message after a reboot. It’s simply a registry key that hasn’t been deleted during the Novell client uninstall process.

Restart the PC in Safe Boot mode. Open the registry and locate the following key:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogonGinaDLL

The value is set to NWGINA.DLL

Double click the GinaDLL key and change the value to MSGINA.DLL

Restart the PC and you should now have a Windows login prompt.
