I am having a problem performing maintenance tasks on Microsoft SQL Server 2008 after changing my server name from the original random name given during installation to the one I prefer
This is the error am getting
Could not obtain Information about Windows NT group/users
'WIN-4N4A9TLBGJJ\Administrator', error code 0x534
Is there a way I can fix this problem without having to delete the account and recreating it again?
First, a little background. I've recently been taken on as a web and software developer for a small company, who has no other in-house IT support. They've been asking my opinion on lots of IT subjects that are quite far out of my comfort zone. I'm definitely not a network admin.
Their IT consultancy contractor is pushing them to upgrade their dedicated exchange server, even though it seems like the one they currently have has a lot of life left in it and is running problem free. They say it's "coming to the natural end of it's life". They want to install a monster with a Xeon E5-2420, 32GB RAM, 2x 1TB HDDs, Windows Server 2012 and Microsoft Exchange 2010. They want to charge a small fortune for it. Basically, this system seems massively over the top seeing as it won't be doing anything else other than running as an exchange server for a company with less than 25 email accounts. My employers also have a file server system in-house that hosts three web apps, an SQL server, their local domain, print server and shared folders. That machine is using the same specs as the proposed new one, and it is barely using any of it's potential.
I asked if Microsoft Exchange 2010 could be installed on their file server, but they said that MS Exchange can't run on the same system as an SQL server because for some reason they will eat up each others resources (even though the SQL server isn't touching 1% of the current system's CPU or RAM).
My question is really, are they trying to rip my employers off? Could MS Exchange be installed on their other server (on a virtual instance or not), or does the old one even need replacing at all? Going with their current suggestion will cost the company in excess of £6k, and it seems entirely unnecessary.
I apologies, because I know this is probably a little thin on details, but if I carry on I could end up writing a massive essay that no-one will want to read. I've been doing my research, but I'm not knowledgeable enough make any hard decisions. Let me know if you need any more details.
Thank you for any help you can offer.
Further Details:
The new exchange would need to support Outlook Web App, 25 users, a few public mailboxes, and email exchange with Blackberries.
I need to create an Active Directory lab that contains printers and test out various printer-related functionality (adding printers in AD, clients attaching to printers, printers, etc)
Is there a good way to properly simulate printers on a network? Or does there need to be real physical printers somewhere that eventually are attached, even if no output comes out.
How would you solve this problem?
Hi there,
I have running a Windows XP SP3 Machine and I can't login after I have locked my Workstation. I changed my password and installed last Updates from Microsoft last Friday.
When Windows comes up, there is no problem to login. But after I locked it, it tells me that my password is wrong.
I pushed the client again into the domain, but doesn't help.
Thanks,

Hi
I try to show the Mail Control Panel item in Windows 2008 R2. I only type the Name "Mail" in to the "Show only specified Contol Panel items Properties" in the Group Policy.
In Windows 2008 R2 that doesn't work and theres no item in the Control Panel to configure Outlook 2010 Profiles. I already tried with: Mail and Mail(32-bit).
I didn't find the suitable entry on on the side: http://msdn.microsoft.com/en-us/library/ee330741%28VS.85%29.aspx#
Kind regards

I recently had to have Microsoft Office 2003 re-installed on my computer.
Suddenly I have duplicate contacts, while some contacts that were even more recently added are not accessible through the TO: area of email messages I want to send.
Can anyone help with this?
Thanks.
How to configure non-admin users to allow them to install updates for Java and Adobe Acrobat Reader without needing for administrator password on Windows 7. Updates for Microsoft products install without problems.

I am having trouble finding such functionalities in Microsoft Powerpoint 2003. I tried googling it but no luck either. Does it exist? Is there an easy way to find keywords in a group of Powerpoint presentation files? Thanks in advance.
So, Microsoft added .NET support to Windows Server 2008 R2 Core, but which is the latest version that is supported? I know it has to be either .NET 3.5 or .NET 3.5 SP1, but which is it?
Which registry keys need to be edited to change the default browser?
I have found these keys so far and they seem to do what I want, but I am not sure if I have found all of them:
Data in:
HKEY_CURRENT_USER\Software\Classes\http\shell\open\command
HKEY_CURRENT_USER\Software\Classes\https\shell\open\command
HKEY_CURRENT_USER\Software\Classes\ftp\shell\open\command
Value in:
HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\MuiCache
Are there any other keys which would need to be changed, so that it is done perfectly?

How to create my own custom action in Microsoft Outlook Rules?
In Outlook, when creating a rule in the Rules wizard, we set first the conditions and then set the actions that we choose from a list of predefined actions. Is there a way to add my own action to the existing actions programmatically?
I also see an action called custom action, when i click it it opens up a small window with an empty combobox, can i add my custom action there, and how?
I have a jar that runs forever (infinite loop with socket listening thread) and need it to run in the background at all times. An example would be: "java -jar test.jar" How do I do this? Thanks in advance!
I am in charge of production servers serving static content for a website. Those servers are constantly being crawled by bots looking for potential exploits (which isn't that much of a problem security-wise because no application can be reached behind the web server) but
generates thousands of 404 per day, sometimes per hour. I am looking into ways of blocking those requests but it's tricky (you want to make sure you don't block legitimate traffic and these bots are becoming more and more clever at looking like they're legit) and is going to take me a while to find an acceptable solution.
In the meantime I would like to reduce the performance impact of serving those 404 pages. Indeed we're using nginx which by default is configured to serve it's 404 page from the disk (This can be changed using the error_page directive but in the end the 404 will either have to be served from disk or from another external source (e.g. upstream application which would be worst)) which isn't ideal.
I ran a test with ab on my local machine with a basic configuration: in one case I echo a message directly from nginx so the disk isn't touched at all, in the other case I hit a missing page and nginx serves its 404 from disk.
server {
# [...] the default nginx stuff
location / {
}
location /this_page_exists {
echo "this page was found";
}
}
Here are the test results (my laptop has Intel(R) Core(TM) i7-2670QM + SSD in case you're wondering why they are so high):
$ ab -n 500000 -c 1000 http://localhost/this_page_exists
Requests per second: 25609.16 [#/sec] (mean)
$ ab -n 500000 -c 1000 http://localhost/this_page_doesnt_exists
Requests per second: 22905.72 [#/sec] (mean)
As you can see, returning a value with echo is 11% ((25609-22905)÷22905×100) faster than serving the 404 page from disk. Accordingly I would like to echo a simple 404 Page not Found string from nginx.
I tried many things so far but they all failed, essentially the idea was this:
location / {
try_files $uri @not_found;
}
location @not_found {
echo "404 - Page not found";
}
The problem is that as soon as the echo directive is used, the http response code is set to 200. I tried changing that by doing error_page 200 = 400 but that breaks the configuration.
How can I serve a 404 page directly from nginx? (without hacking the source which may be might next step)
This is almost certainly a dumb question, but... say I have Windows 7, with some anti-virus software installed, and I am using Microsoft's Windows XP Mode to run some legacy applications as well. Is there any reason why I would want to install an anti-virus program in XP mode as well?
I try to use the php ftp_connect fucntion on my dedicated server and I'm unable to establish a connection:
$conn_id = ftp_connect($ftp_server, 21) or die("Unable to connect to $ftp_server") ;
I'm sure the function is available as I test with :
function_exists('ftp_connect')
and it returns true
When I ftp the server through the shell I can reach it so I guess it's not a firewall issue.
Am I missing something else ?
Thanks for your precious advices
In the SuSE /etc/crontab the entry to run the cron.{hourly,daily,monthly,weekly} scripts is coded as:
-*/15 * * * * root test -x /usr/lib/cron/run-crons && /usr/lib/cron/run-crons /dev/null 2&1
Notice that the very first character of the specification is a dash character (-), and this is NOT a typo.
Can somebody explain what the time spec '-*/15' means?
BTW, the stuff seems to be running fine.
Thanks
I'm looking to install Lubuntu 10.04 onto my flash drive to test it out without the risk of altering my system which runs Windows 7. I think I need what is called a "persistant install", so that Lubuntu will run off of my flash drive and any changes made will stay there, unlike the demo feature of the CD.
Sometimes it is useful to have e-mail address like [email protected], where randomnumber identifies the conversation between a robot such as a mailing list server and a user. Is this possible with Microsoft Exchange?
We have 2 different locations, and at both site we have multiple domain controllers (Win2008).
In our application we use Serverless Binding to execute our LDAP queries http://msdn.microsoft.com/en-us/library/ms677945(v=vs.85).aspx.
If we look at de DnsHostName of the LDAP://RootDse on site B we always get the default domain controller of site A. Therefor all LDAP queries go much slower.
Is there a way to change the default domain controller per site ?
Webcams and headphones from Microsoft (like for example the LifeChat ZX-6000, in my case) have a button which can be used only with Windows Live Messenger, to answer a call.
There is no option provided to configure it so that it would launch a program, or work in another communicator, in the given drivers.
Is there a way to make it work with Skype, so that I can answer a call by pressing this button? Maybe there are other drivers?
A friend of mine has purchased a new laptop (Toshiba) with Windows 7 installed and has also purchased Outlook 2007 and atttmped to install it - the install worked ok, but I think he may have selected Exchange server when installing the first time - now it will not start, displaying message like "Your Microsoft Exchange Server is unavailable "
Outlook 2007 should have been configued for Pop3 as he has a hotmail account, but Outlook will not load "offline" and despite me de-installing, re-installing, running repair, I cannot get it to load to a point where I can add a new email account.
If any one has any ideas on this, I would apprecaite the help
Thanks,
Bob
