Unable to create VMFS partition

Well, ran into an issue where we couldn't create a datastore on our freshly set up array. A lot of people said the solution was to install windows and format the disks with NTFS. While that might work, I didn't want to do that. You have a couple of other options You can use a Windows Vista/7/2008/2008r2 install disk and after you click the first install button, press Shift+F10 to get a command prompt. You can then use DiskPart. Or, if you would rather do this in the ESX shell try zeroing out

Group policy extensions and shortcuts

Well, here's the task, create a shortcut that would apply to certain people using group policy extension that point to a file or executable on a mapped drive...trickier than it sounds. Here's the reason it doesn't work and a workaround. When creating a file system shortcut, it first checks to see if the target exists or not. When you use a UNC path \\server\share\file it is connected to as the local system, not the current user. So, check the Run as user context box. That was flaky for me. Some

Outlook 2011 on the Mac and Exchange 2007+

Had an issue today where the Outlook client on a mac out on the internet would not connect to our exchange server. Turns out that Outlook 2011 requires access to the EWS web services, and probably all other Outlook Anywhere services. We had disabled Outlook Anywhere from the outside, because Outlook on the desktops worked just fine. Once we enabled it for the users, it worked great.

DNS Intermittently not resolving domains

We've run into a problem where some domains would stop resolving from Windows DNS. They would work fine for about a week, then they would stop. I couldn't find anything on the internet, and MS's support people had me try changing the CacheLocking stuff (disable it) by running dnscmd /config /cachelockingpercent 0 then restarting the DNS server. That will disable the cachelocking. Cache locking is basically saying, don't overwrite the cache until the percent of the ttl has expired. Even if it ch

Nested group file permissions not taking effect

Alright, here was my problem. I have a 2008r2 file server, tons of files, and we are removing everyone's full access rights and doing 3 groups for each root folder, a full control, modify and read only. We ran into a problem where if you put a user in one of the groups to give them access, they still would not have access. The fix, sort of simple, but dumb. For us, a simple log off and log on of the user didn't fix it. We had to go in after they tried, using computer management, close their conn

RSA Agent Access Denied/Time outs with NLB

RSA agent on servers getting access denied and network timeout problems when the server is using NLB. Authentication Failures during test.While installing some RSA agents on NLB systems I ran into a problem where only one of the nodes would succesfully test the authentication. I started thinking, ok, maybe it is the nlb, so I set the client to use the dedicated ip. Nope, still didn't. So googling around I found half of my answer, use the NLB ip address. So Inside of the RSA server Security Conso

Server manager not displaying roles/features

There was an event log error entry every time I tried in the Application event log. It was: Faulting application name: TrustedInstaller.exe, version: 6.1.7600.16385, time stamp: 0x4a5bc4b0 Faulting module name: ntdll.dll, version: 6.1.7600.16385, time stamp: 0x4a5be02b Exception code: 0xc00000fd Fault offset: 0x00000000000529f0 Faulting process id: 0x9a0 Faulting application start time: 0x01cb52a9177986b4 Faulting application path: C:\Windows\servicing\TrustedInstaller.exe Faulting modul

TMG cannot handle your request because the DNS quota was exceeded

Just yesterday I started to get this error message Error Code: 500 Internal Server Error. Forefront TMG cannot handle your request because the DNS quota was exceeded. Contact your Forefront TMG administrator. (12218) while browsing the internet. I could not find any information on this message at Microsoft or anywhere else on Google. Well. I think I know what it was. It has to do with 2008r2's DNS not responding to all requests after a while. I had changed all sorts of things trying to get it to

Changing SMTP 220 Header in Exchange 2010

OK, problem, the exchange 2010 server was spewing out the internal server name in the header of a SMTP connection 220 internal.domain.local Microsoft ESMTP MAIL Service ready at Sun, 15 Aug 2010 03:23:18 -0400. Needless to say, that's bad. I wanted it to show the external name of the server. So, I set out to find it. Turns out you can't do it through the Management Console. You have to pop open the management shell. You can get the name using the management console, or to find it using the mana

"no network provider accepted the given network path"

I ran into a problem where I had one 2003r2 server that couldn't access the Linux samba servers but it could access the other windows server with no problems. I was using share level security in the smb.conf file. This worked fine up until about a month ago, only found out today because we needed to get something off of the backup server, which, well, since it couldn't access it, there is no backups...besides the point. Anyways. Here's the steps that DID NOT WORK * Reboot (should always be eve

Temporary file attributes and DFS(R)

We are using DFS-R on our servers to replicate DNN content between multiple servers. It works really well, except for some of our system create PDF documents with the temporary file attribute set. Turns out that DFS will not replicate files with the Temporary file attribute. Lame. I created a simple PowerShell script that will recurse through everything in the sub folders and if it's the attribute is set, it will remove it. Because the attribute changes, it causes the file to sync between the 2

DNN and Asp.net 4.0 Broken Captcha.aspx and LinkClick.aspx

Well, I ran into a problem with my captcha stuff on my blog, it wasn't working. Just displaying a red X. I am on a 2008 R2 server with IIS7.5 and .NET 4.0 64-bit. The fix was simple. I had to change the handlers in the web.config. Specifically the preconditions. The used to be integratedMode,runtimeVersionv2.0. You can either change them to integratedMode,runtimeVersionv4.0 or just remove them. In the section, remove the preCondition stuff from the entries pertaining to dotnetnuke. All of mine

L2TP ports getting changed back to routing only with ISA/TMG

I have had a problem where my TMG servers where having their L2TP ports switched back to the routing every time they rebooted or TMG settings where changed, turns out that it was a setting in the TMG server causing the problem. In the Remote Access Policy (VPN) section, there is "Verify VPN Properties" option, I clicked that and saw that L2TP was not checked. So I checked it, and poof, now they get set as RAS/Routing. But, that only fixed one of the 2 servers. The problem on the second server ha

CDO.Message on domain user in IIS6

Well, we started moving websites from a network server/local system hosting into their own locked down user account. The way it should have been in the beginning. We ran into a problem where sites that were using the CDO.Message com object couldn't send e-mails. They were getting an error saying that SendUsing configuration error. This one: Issue: Number=-2147220502(0x800403EA) App [1002] Source=CDO.Message.1 Description= -2147220960[0x80040220] The "SendUsing" configuration value is invalid W
