• can the remote app rd web access be accessed from my local system

  - by shiva

  I am new to the remote app remote desktop access. I can access the application that i have published from my server using the link FQDN\rdweb. But on trying to access the same url from my local system(outside the server domain, say from my home pc) i get a not found error. Is there anything that i need to change in my local system to be able to access the remote applications? Or is it that for accessing webapps i need to be logged into the server? Please help me understand this

• Windows Server 2008 R2 running at a snail's pace

  - by Django Reinhardt

  Really weird problem here. Our main web server has started running at a snail's pace, for absolutely no reason we can discern. Even after restarting the machine, when there's no little or no ram usage and CPU usage is fluctuating between 0 and 30%, simple tasks, like opening Internet Explorer, or waiting for My Computer to open, take forever. There are no processes hogging system resources that we can see... the machine itself is just exhibiting extremely slow behaviour. I've never seen a machine do this. A lot of security updates had built up, so we decided to let Windows install them. When we looked through the history upon restarting, though, they had failed with error code 800706BA. I don't know if this could be related or not. Any help in this matter would be greatly appreciated. As mentioned in the title, we're running a Windows Server 2008 R2 machine. It's also running SQL Server and IIS. It has 16GB of RAM and a decent Quad Core processor. It's also been fine until now -- and we haven't changed a thing. Thanks for any help.

• how to copy sql server database on same server

  - by Sam

  I've got a SQL Server 2008 and want to make a copy of a database so I've got a 2nd Version of the database for testing on the same server. The database copy wizard is not able to copy the database, it always sends funny error Messages about missing objects (using SMO copy). When I try to make a backup and restore it under a different database name it still keeps the file names of the original database and overrides this (crashing the original database). So how do I copy a SQL database? Shutdown SQL Server, copy the physical files and attach them? Maybe a command line tool for database copy? Shouldn't there be an easy way to make a copy?

• Server 2003 and SSL Certificates

  - by Keith Stokes

  I have a Windows 2000 domain with dozens of Windows 2000 servers and a few 2003 servers. Each server runs a custom app talking to a 3rd party utilizing self-signed certificates. To help troubleshooting we've created a custom test app. The 2000 servers are able to talk within seconds. The 2003 servers take anywhere from 10-30 seconds using a domain account and much less, usually under 5 seconds using a local account. The only exception to the local account performance is a new account, which is slow initially then faster. If you leave the test app open and reconnect repeatedly it talks in seconds. If you leave it open for sometime between 1 and 2 hours, it reverts back to the previous 10 seconds, so obviously something is caching. Installing the destination certificates in the local 2003 server store makes no difference. I've installed the certificates in AD and that apparently makes domain accounts work in 9-12 seconds, vs 30 seconds that was regular before. Manually clearing the certificate store on the 2003 server makes no difference. I'm at a loss as to where the certs might be cached and if I'm using some sort of domain certificate store that's hiding from me.

• sql server 2005 instance unresponsive and all db's are 'in recovery'

  - by user44650

  we've got a sql server 2005 instance that one of our guys messed up, i believe they killed the sql server service and restarted the computer, and when it came back all of our databases are "in recovery" and it times out every time we try to connect to it. it's been 'in recovery'and unable to connect to 'msbd' (also in recovery) whenever we try to use SSMC, for the last 4 days now. i'm unsure how to use the DBCC CHECKDB command to check the db integrity. we have backups(which we can't recover from because it keeps timing out), and it's a testing server, so nothing in production is really lost. is there any way to get it out of recovery mode? we have another sqlserver instance running that's just fine, but this instance keeps timing out. the errors i keep seeing are database msdb is being recovered. wait until recovery is finished and an exception occurred while executing a transact-sql statement or batch Timeout expired. any thoughts? we don't really have a DBA here, or anyone with much sql experience.

• Symantec Backup exec 2012 for SBS - moving data to offsite drives

  - by Will Lennard

  Can anyone advise how best to run the following strategy, or even if it is possible/sensible strategy? I am looking to backup an SBS server using BE2012 where the data is backed up on a weekly full backup, with subsequent daily incrementals till the end of the week, a fresh full backup will then be taken the next weekend, and the cycle repeats for 4 weeks, thus 4 full backups with incrementals. This months worth of backups will then be moved off to an offsite store via USB drive for safe keeping. Is this viable, sensible, or am i just a bit crazy? All ideas are welcome.

• Script to mirror MS SQL Server databases between 2 servers

  - by David W

  Hi I have about 200 sites each of which have 2 servers running MSSQL (2k5 at some sites, 2k8 at others) One server is production and the other is primarily there as a backup. We're rebuilding all of these servers this year and as part of that we will have to set up mirroring for ... a lot ... of databases. Some of these sites have 45 databases so mirroring them manually is going to be a huge pain. I was going to write a batch script which uses SQLCMD to backup the database and log, copies to the secondary server, restores the backup and log with norecovery, creates the endpoints and sets the partner. This in itself isn't too complicated, but i'd love to see what other people have done as i'm not very confident in catching errors using the process i've outlined above. I've seen Tools to manage sql 2008 database mirroring? Which looks really good, but the formatting is jumbled and I can't get it to work. If anyone has any other scripts they've written and are willing to share I'd be eternally grateful. Ideally I'd love to be able to use a script to ensure there are matching endpoints (same ports) on both servers, backup the database, backup the log, copy the backups to second server, restore database and log with norecovery, set the partners on both servers, and somehow confirm that the databases are linked and synchronized. Well, thanks for reading :)

• Terminal Server CPU usage at 100%

  - by Light1c3

  I'm running a terminal server with around 50-60 users,and every so often the server will go from 40% usage to 100%. I took a closer look an it seems every time this happens, a different user or two seem to be caught in a loop and end up using < 30% where the rest of the users only use a maximum of 5%. The company behind the software we use clame it's due to the servers inadequate hardware (It's a VM system running on a dual - quad core setup) which to me sounds like BS! I'm fairly new to this level of IT so if I misspoke I apologize. I have no way to prove it but I believe adding more raw hardware power wont do me any good as this to me seems like a bug in their software, and it will suck up as much ( or little) CPU as it's given. The VM in question has 4 vCPU cores and 12 GB RAM available, and is running Windows Server 2008, 64-bit Thanks in advance for your help! Note: I have the same question posted on SO, but was pointed in this direction so just in case, here is a link to the post http://stackoverflow.com/questions/17276602/termserver-cpu-at-100

• How to monitor RAM usage for Hyper-V VMs ?

  - by Mac

  A bit of context first : on Windows 2008 Standard x64 with 8Gb RAM, I have 5 VMs running which should take up 1664Mb RAM (3*256Mb+384Mb+512Mb). There is nothing else running on this server except the basic OS components (this not a Core installation). I know that each VM will use more RAM on the host than what has been configured in Hyper-V. But when I run the task manager, it says 6.7Gb used ! If I sum up the RAM used by each process in the task manager (showing all users processes), I get to something around 1Gb... So : how can I check how much RAM each VM is really using on the host (it does not seem to be available via task manager) ? Note that I am aware of the fact that my problem could be unrelated to VM RAM usage, but I would still very much like to know how to do this.

• KVM vs Hyper-V. Which hypervisor is best for windows guests?

  - by user198851

  I am currently testing openstack for windows guests (XP and 7). I have deployed openstack "all in one" on system with following specs Processor corei5. (4 physical cores and 8 Threads with HT Technology) RAM 8 GB. HD 500 GB. I have created 4 windows xp guests with 512MB RAM and 1VCPU. On each windows guest i have installed visual studio 2008 only. In nova.conf CPU Over-Commit ratio is 2 for better performance (as mentioned in openstack operation guide). Using KVM as hyerpvisor. I have observed poor performance when simultaneously using visual studio in four windows instances. How i can improve performance ? Should i use KVM or Hyper-V ? or any other suggestion ?

• Client side latency when using prediction

  - by Tips48

  I've implemented Client-Side prediction into my game, where when input is received by the client, it first sends it to the server and then acts upon it just as the server will, to reduce the appearance of lag. The problem is, the server is authoritative, so when the server sends back the position of the Entity to the client, it undo's the effect of the interpolation and creates a rubber-banding effect. For example: Client sends input to server - Client reacts on input - Server receives and reacts on input - Server sends back response - Client reaction is undone due to latency between server and client To solve this, I've decided to store the game state and input every tick in the client, and then when I receive a packet from the server, get the game state from when the packet was sent and simulate the game up to the current point. My questions: Won't this cause lag? If I'm receiving 20/30 EntityPositionPackets a second, that means I have to run 20-30 simulations of the game state. How do I sync the client and server tick? Currently, I'm sending the milli-second the packet was sent by the server, but I think it's adding too much complexity instead of just sending the tick. The problem with converting it to sending the tick is that I have no guarantee that the client and server are ticking at the same rate, for example if the client is an old-end PC.

• SQL Server: Must numbers all be specified with latin numeral digits?

  - by Ian Boyd

  Does SQL server expect numbers to be specified with digits from the latin alphabet, e.g.: 0123456789 Is it valid to give SQL Server digits in other alphabets? Rosetta Stone: Latin: 01234567890 Arabic: ?????????? Bengali: ?????????? i know that the client (ADO) will convert 8-bit strings to 16-bit unicode strings using the current culture. But the client is also converting numbers to strings using their current culture, e.g.: SELECT * FROM Inventory WHERE Quantity > ???,?? Which throws SQL Server for fits. i know that the server/database has it's defined code page and locale, but that is for strings. Will SQL Server interpret numbers using the active (or per-login specified) locale, or must all numeric values be specifid with latin numeral digits?

• Windows Server 2003 RDP not listening on IPv6

• SQL SERVER – Weekly Series – Memory Lane – #048

  - by Pinal Dave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Order of Result Set of SELECT Statement on Clustered Indexed Table When ORDER BY is Not Used Above theory is true in most of the cases. However SQL Server does not use that logic when returning the resultset. SQL Server always returns the resultset which it can return fastest.In most of the cases the resultset which can be returned fastest is the resultset which is returned using clustered index. Effect of TRANSACTION on Local Variable – After ROLLBACK and After COMMIT One of the Jr. Developer asked me this question (What will be the Effect of TRANSACTION on Local Variable – After ROLLBACK and After COMMIT?) while I was rushing to an important meeting. I was getting late so I asked him to talk with his Application Tech Lead. When I came back from meeting both of them were looking for me. They said they are confused. I quickly wrote down following example for them. 2008 SQL SERVER – Guidelines and Coding Standards Complete List Download Coding standards and guidelines are very important for any developer on the path of a successful career. A coding standard is a set of guidelines, rules and regulations on how to write code. Coding standards should be flexible enough or should take care of the situation where they should not prevent best practices for coding. They are basically the guidelines that one should follow for better understanding. Download Guidelines and Coding Standards complete List Download Get Answer in Float When Dividing of Two Integer Many times we have requirements of some calculations amongst different fields in Tables. One of the software developers here was trying to calculate some fields having integer values and divide it which gave incorrect results in integer where accurate results including decimals was expected. Puzzle – Computed Columns Datatype Explanation SQL Server automatically does a cast to the data type having the highest precedence. So the result of INT and INT will be INT, but INT and FLOAT will be FLOAT because FLOAT has a higher precedence. If you want a different data type, you need to do an EXPLICIT cast. Renaming SP is Not Good Idea – Renaming Stored Procedure Does Not Update sys.procedures I have written many articles about renaming a tables, columns and procedures SQL SERVER – How to Rename a Column Name or Table Name, here I found something interesting about renaming the stored procedures and felt like sharing it with you all. The interesting fact is that when we rename a stored procedure using SP_Rename command, the Stored Procedure is successfully renamed. But when we try to test the procedure using sp_helptext, the procedure will be having the old name instead of new names. 2009 Insert Values of Stored Procedure in Table – Use Table Valued Function It is clear from the result set that , where I have converted stored procedure logic into the table valued function, is much better in terms of logic as it saves a large number of operations. However, this option should be used carefully. The performance of the stored procedure is “usually” better than that of functions. Interesting Observation – Index on Index View Used in Similar Query Recently, I was working on an optimization project for one of the largest organizations. While working on one of the queries, we came across a very interesting observation. We found that there was a query on the base table and when the query was run, it used the index, which did not exist in the base table. On careful examination, we found that the query was using the index that was on another view. This was very interesting as I have personally never experienced a scenario like this. In simple words, “Query on the base table can use the index created on the indexed view of the same base table.” Interesting Observation – Execution Plan and Results of Aggregate Concatenation Queries Working with SQL Server has never seemed to be monotonous – no matter how long one has worked with it. Quite often, I come across some excellent comments that I feel like acknowledging them as blog posts. Recently, I wrote an article on SQL SERVER – Execution Plan and Results of Aggregate Concatenation Queries Depend Upon Expression Location, which is well received in the community. 2010 I encourage all of you to go through complete series and write your own on the subject. If you write an article and send it to me, I will publish it on this blog with due credit to you. If you write on your own blog, I will update this blog post pointing to your blog post.

Here is the one of those examples. For example “Our business requirement is when we add new column we want it unique across current database.” Read the solution to this strange request in this blog post. Excel Losing Decimal Values When Value Pasted from SSMS ResultSet It is very common when users are coping the resultset to Excel, the floating point or decimals are missed. The solution is very much simple and it requires a small adjustment in the Excel. By default Excel is very smart and when it detects the value which is getting pasted is numeric it changes the column format to accommodate that.

• How mod_cache working with "must-revalidate" and "max-age"?

  - by Dmitriy Sosunov

  Quick question before I will explain my flow: ?an mod_cache perform revalidate with if-none-match only if max-age is expired in case if it configured in reverse proxy mode? My goal is to reduce a number of revalidation requests to our the origin server. For instance: The first request goes to the origin server and then mod_cache save a response in to the cache according to header cache-control: max-age. And only when max-age is expired then mod_cache will revalidate with if-none-match. Currently, mod_cache revalidate each request, regardless that max-age is defined or not. My configuration of Apache 2.4.3 (Windows), on linux I see the same behavior that I will show below. ServerName proxy.lo ProxyRequests Off ProxyPreserveHost Off Header set Vary "Accept, Content-Type, Content-Encoding, Accept-Language" RequestHeader set X-Forwarded-Proto "http" # modify header for user agent's Header set Cache-Control "private, no-cache, no-store, no-transform" CacheQuickHandler off CacheDefaultExpire 300 # the origin server do not provide last-modified CacheIgnoreNoLastMod On CacheIgnoreCacheControl On # the origin server define cache-control: private, no-store only for user agents # Therefore, I would like ignore those headers on the proxy server. CacheStorePrivate On CacheStoreNoStore On CacheEnable disk / CacheRoot "C:/Apache.Cache" CacheDirLevels 5 CacheDirLength 4 CacheMinExpire 15 CacheDetailHeader on CacheHeader on KeepAlive Off ProxyPass / http://origin.lo/ ProxyPassReverse / http://origin.lo/ Also, I have turned on debug log level to see how mod_cache handles a content for caching: I provided this to show that mod_proxy always decides that a content isn't fresh. Why?I provided this to show that mod_proxy always decide that a content isn't fresh. Why? max-age was provided (see below).

N.B. Apache 2.4.3 Thanks, I would be grateful for any help.

• Apache2 graceful restart stops proxying requests to passenger

  - by Rob

  Issue with apache mod proxy, it stops proxying requests after a graceful restart but not all the time. It seems to happen only on a Sunday when a graceful restart is triggered by logrotate.

• What are the possible disadvantages of enabling the "data access" server option in sys.servers for t

  - by Corp. Hicks

  We plan to change the default server options of an SQL2k5 server instance by enabling data access. The reason is that we want to run "SELECT * FROM OPENQUERY(LOCALSERVER, '...')" -like statements on the server. What are the possible disadvantages of enabling server option "data access" (alias sys.servers.is_data_access_enabled) for the local server (sys.servers.server_id = 0)? (There must be a reason for MS setting this option to disabled by default...) EDIT: it turns out that I'm not the first person to ask this question: http://sqlblogcasts.com/blogs/piotr_rodak/archive/2009/11/22/data-access-setting-on-local-server.aspx "The DATA ACCESS server option is not very well documented in my opinion - the Books On Line say it is a property of linked servers. It doesn't mention at all that you actually can have it enabled on your local server to enable OPENQUERY calls. I noticed that when you disable DATA ACCESS on a linked server, you can't query any table located on it (I tested it on my loopback server) neither using OPENQUERY nor four-part naming convention. You can still call procedures (with four-part naming) that return rowsets. Well, the interesting question is why it is disabled by default on local server - I suppose to discourage users from using OPENQUERY against it." It also seems that the author of the post (Pjotr Rodak) is a Stack Overflow user :-)

• HP Proliant DL380 G4 - Can this server still perform in 2011?

  - by BSchriver

  Can the HP Proliant DL380 G4 series server still perform at high a quality in the 2011 IT world? This may sound like a weird question but we are a very small company whose primary business is NOT IT related. So my IT dollars have to stretch a long way. I am in need of a good web and database server. The load and demand for a while will be fairly low so I am not looking nor do I have the money to buy a brand new HP Dl380 G7 series box for $6K. While searching around today I found a company in ATL that buys servers off business leases and then stripes them down to parts. They clean, check and test each part and then custom "rebuild" the server based on whatever specs you request. The interesting thing is they also provide a 3-year warranty on all their servers they sell. I am contemplating buying two of the following: HP Proliant DL380 G4 Dual (2) Intel Xeon 3.6 GHz 800Mhz 1MB Cache processors 8GB PC3200R ECC Memory 6 x 73GB U320 15K rpm SCSI drives Smart Array 6i Card Dual Power Supplies Plus the usual cdrom, dual nic, etc... All this for $750 each or $1500 for two pretty nicely equipped servers. The price then jumps up on the next model up which is the G5 series. It goes from $750 to like $2000 for a comparable server. I just do not have $4000 to buy two servers right now. So back to my original question, if I load Windows 2008 R2 Server and IIS 7 on one of the machines and Windows 2008 R2 server and MS SQL 2008 R2 Server on another machine, what kind of performance might I expect to see from these machines? The facts is this series is now 3 versions behind the G7's and this series of server was built when Windows 200 Server was the dominant OS and Windows 2003 Server was just coming out. If you are running Windows 2008 R2 Server on a G4 with similar or less specs I would love to hear what your performance is like.

• Could I use Windows 7 instead of Windows SBS 2008 for this server?

  - by Ecyrb

  First off, I'm not a sys admin. I'm just a software developer trying to help out my parents' small business. Right now they have one server, a domain controller with a P4 processor running SBS 2003. They also have this machine hosting QuickBooks, MySQL for the old version of an app, and SQL Server 2008 Express for the new version of the app (which will replace the old eventually). They've been complaining about the workstations being slow so I figured it might help if they bought a new server and moved QuickBooks, MySQL, and SQL Server to the new server, leaving the old server as just a DC. In trying to pick an operating system for their new server, I was thinking about Windows SBS 2008 Standard with enough licenses for seven machines. But that's a lot more money than they're going to want to spend. So then I wondered if there's any real advantage to having a server OS as opposed to just throwing Windows 7 on the new server. It's a lot cheaper and I can't think of any SBS features that it would need if it's just hosting QuickBooks, MySQL, and SQL Server. Would it be okay to use Windows 7 for a server like this? Are there any advantages to using SBS 2008 that I would be missing out on? Any additional tips are much appreciated!

• vmware server 64 bit on ubuntu 9.10 64 bit with P2V windows 2003 SBS poor network speed

  - by RobertHC

  configuration is ubuntu 2.6.31-21 64 bit vmware 2.0.2 64 bit last release hardware is core 2 quad with 8GB ram guest is win 2003 server SBS 32 bit Dear friends, we have a converted physical to virtual windows sbs 2003, converted with last converter available nowadays http://www.vmware.com/products/converter/ vCenter converter. Running the P2V 2K3 SBS on vmware server, it does boot fine, but we do note an abnormal CPU activity and a poor lan speed. As attempts we did what follow. We removed all unneeded peripherals, we removed one NIC (phisycal server was 2 nics), we changed the vmx to ged the nic recognized as intel instead than amd, we removed 1 cpu (physical was 2 cpu), we removed anything was reported as failed driver from system events monitor. Nothing to do, no way and funny results. Let's read some tests results. All are made with the same file copied in different source folders. Copying from client side (both directions copy, to/from server) results are i.e. 10 seconds, copying the same files from server side (again from and to server) results are different... from client to server, speed is round about (bit more) 10 seconds, but from server to client direction is slower: double the time. Beeing very fast and launching a simultaneous copy "from server to client"+"from client to server", this made from the server side, results in a stuck traffic... 45 seconds to do the copy. vmware tools are installed and e1000 driver has been updated. With one processor CPU activity is still going up and down but much less than with two. Because of test, we installed win 2k8 STD 64 bit. We repeated all the above tests with exactly the same file result is just one: always 5 seconds (this matches the lan speed) Any idea about this issue is welcome and thank you if any. Kind regards R.

• SignalR Server Error "The ConnectionId is in the incorrect format." with SignalR-ObjC Library

  - by ozzotto

  Before asking a separate question I've done lots of googling about it and added a comment in the already existing stackoverflow question. I have a SignalR Hub (tried both v. 1.1.3 and 2.0.0-rc) in my server with the below code: [HubName("TestHub")] public class TestHub : Hub { [Authorize] public void TestMethod(string test) { //some stuff here Clients.Caller.NotifyOnTestCompleted(); } } The problem persists if I remove the Authorize attribute. And in my iOS client I try to call it with the below code: SRHubConnection *hubConnection = [SRHubConnection connectionWithURL:_baseURL]; SRHubProxy *hubProxy = [hubConnection createHubProxy:@"TestHub"]; [hubProxy on:@"NotifyOnTestCompleted" perform:self selector:@selector(stopConnection)]; hubConnection.started = ^{ [hubProxy invoke:@"TestMethod" withArgs:@[@"test"]]; }; //received, error handling [hubConnection start]; When the app starts the user is not logged in and there is no open SignalR connection. The users logs in by calling a Login service in the server which makes use of WebSecurity.Login method. If the login service returns success I then make the above call to SignalR Hub and I get the server error 500 with description "The ConnectionId is in the incorrect format.". The full server stacktrace is the following: Exception information: Exception type: InvalidOperationException Exception message: The ConnectionId is in the incorrect format. at Microsoft.AspNet.SignalR.PersistentConnection.GetConnectionId(HostContext context, String connectionToken) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.Hubs.HubDispatcher.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(IDictionary`2 environment) at Microsoft.Owin.Mapping.MapMiddleware.<Invoke>d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContext.EndFinalWork(IAsyncResult ar) at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Request information: Request URL: http://myserverip/signalr/signalr/connect?transport=webSockets&connectionToken=axJs EQMZxpmUopL36owSUkdhNs85E0fyB2XvV5R5znZfXYI/CiPbTRQ3kASc3 mq60cLkZU7coYo1P fbC0U1LR2rI6WIvCNIMOmv/mHut/Unt9mX3XFkQb053DmWgCan5zHA==&connectionData=[{"Name":"testhub"}] Request path: /signalr/signalr/connect User host address: User: Is authenticated: False Authentication Type: Thread account name: IIS APPPOOL\DefaultAppPool Thread information: Thread ID: 14 Thread account name: IIS APPPOOL\DefaultAppPool Is impersonating: True Stack trace: at Microsoft.AspNet.SignalR.PersistentConnection.GetConnectionId(HostContext context, String connectionToken) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.Hubs.HubDispatcher.ProcessRequest(HostContext context) at Microsoft.AspNet.SignalR.PersistentConnection.ProcessRequest(IDictionary`2 environment) at Microsoft.Owin.Mapping.MapMiddleware.<Invoke>d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at Microsoft.Owin.Host.SystemWeb.IntegratedPipeline.IntegratedPipelineContext.EndFinalWork(IAsyncResult ar) at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) I understand this is some kind of authentication and user identity mismatching but up to now I have found no way of solving it. All other questions suggest stoping the opened connection when the user identity changes but as I mentioned above I have no open connection before the user logs in successfully. Any help would be much appreciated. Thank you.

• Time Service will not start on Windows Server - System error 1290

  - by paradroid

  I have been trying to sort out some time sync issues involving two domain controllers and seem to have ended up with a bigger problem. It's horrible. They are both virtual machines (one being on Amazon EC2), which I think may complicate things regarding time servers. The primary DC with all the FSMO roles is on the LAN. I reset its time server configuration like this (from memory): net stop w32time w23tm /unregister shutdown /r /t 0 w32tm /register w32tm /config /manualpeerlist:”0.uk.pool.ntp.org,1.uk.pool.ntp.org,2.uk.pool.ntp.org,3.uk.pool.ntp.org” /syncfromflags:manual /reliable:yes /update W32tm /config /update net start w32time reg QUERY HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config /v AnnounceFlags I checked to see if it was set to 0x05, which it was. The output for... w32tm /query /status Leap Indicator: 0(no warning) Stratum: 1 (primary reference - syncd by radio clock) Precision: -6 (15.625ms per tick) Root Delay: 0.0000000s Root Dispersion: 10.0000000s ReferenceId: 0x4C4F434C (source name: "LOCL") Last Successful Sync Time: 10/04/2012 15:03:27 Source: Local CMOS Clock Poll Interval: 6 (64s) While this was not what was intended, I thought I would sort it out after I made sure that the remote DC was syncing with it first. On the Amazon EC2 remote replica DC (Windows Server 2008 R2 Core)... net stop w32time w32tm /unregister shutdown /r /t 0 w32time /register net start w32time This is where it all goes wrong System error 1290 has occurred. The service start failed since one or more services in the same process have an incompatible service SID type setting. A service with restricted service SID type can only coexist in the same process with other services with a restricted SID type. If the service SID type for this service was just configured, the hosting process must be restarted in order to start this service. I cannot get the w32time service to start. I've tried resetting the time settings and tried to reverse what I have done. The Ec2Config service cannot start either, as it depends on the w32time service. All the solutions I have seen involve going into the telephony service registry settings, but as it is Server Core, it does not have that role, and I cannot see the relationship between that and the time service. w32time runs in the LocalService group and this telephony service which does not exist on Core runs in the NetworkService group. Could this have something to do with the process (svchost.exe) not being able to be run as a domain account, as it now a domain controller, but originally it ran as a local user group, or something like that? There seem to be a lot of cases of people having this problem, but the only solution has to do with the (non-existant on Core) telephony service. Who even uses that?

• Project Server 2007 install issue - ProjectEventService won't start

  - by Brian Meinertz

  Trying to install PS2007 with SP1 on Server 2003. The install goes fine, but when running the SharePoint Configuration Wizard, it fails at stage 6 of 12 with the error: Failed to register SharePoint Services. An exception of type System.InvalidOperationException was thrown. Additional exception information: Cannot start service ProjectEventService on computer '.'. From the PSCDiagnostics log: Exception: System.InvalidOperationException: Cannot start service ProjectEventService on computer '.'. --- System.ComponentModel.Win32Exception: The service did not respond to the start or control request in a timely fashion. The ProjectEventService (Microsoft Office Project Server Event) won't even start manually using the Network Service account. Starting the service with a domain account works, but subsequently running the Config Wizard causes the service to be removed and re-provisioned to run using the Network Service account, which again fails. Presumably Network Service needs elevated permissions, but even adding it to the local Admin group makes no difference. Anyone come across this sort of issue before?

• VMWare server host agent service won't start

  - by Bimo Arioseno

  I'm using VMWare Server 2.0 on Windows Server 2003 R2. Sometimes after restarting the host machine, the VMWare host agent service won't start due to an error. This is the error messages from Event Viewer: [Service control manager] Timeout (30000 milliseconds) waiting for the VMware Host Agent service to connect. [Service control manager] The VMware Host Agent service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. I've set the service to automatically restart after subsequent failure using services.msc (using a 10 min. delay), but it still won't start. Only starting the service manually seems to work. Has anyone experienced this before? What workarounds or fixes are there?

• Server 2003 on domain wont let domain user have local profile

  - by RobW

  I have a few servers that are acting in this behavior, you log in and always get put into a temporary profile. The server is licensed for TS. The user I am testing with has local admin rights so it doesn't seem to be a permission issue on the server. I'll first get a message that the users roaming profile cannot be found, even though we dont use roaming profiles. I then get another message immediately after saying a local profile could not be loaded, so it will only use a temp profile. Any help would be greatly appreciated.
