• You Probably Already Have a “Private Cloud”

  - by BuckWoody

  I’ve mentioned before that I’m not a fan of the word “Cloud”. It’s too marketing-oriented, gimmicky and non-specific. A better definition (in many cases) is “Distributed Computing”. That means that some or all of the computing functions are handled somewhere other than under your specific control. But there is a current use of the word “Cloud” that does not necessarily mean that the computing is done somewhere else. In fact, it’s a vector of Cloud Computing that can better be termed “Utility Computing”. This has to do with the provisioning of a computing resource. That means the setup, configuration, management, balancing and so on that is needed so that a user – which might actually be a developer – can do some computing work. To that person, the resource is just “there” and works like they expect, like the phone system or any other utility. The interesting thing is, you can do this yourself. In fact, you probably already have been, or are now. It’s got a cool new trendy term – “Private Cloud”, but the fact is, if you have your setup automated, the HA and DR handled, balancing and performance tuning done, and a process wrapped around it all, you can call yourself a “Cloud Provider”. A good example here is your E-Mail system. your users – pretty much your whole company – just logs into e-mail and expects it to work. To them, you are the “Cloud” provider. On your side, the more you automate and provision the system, the more you act like a Cloud Provider. Another example is a database server. In this case, the “end user” is usually the development team, or perhaps your SharePoint group and so on. The data professionals configure, monitor, tune and balance the system all the time. The more this is automated, the more you’re acting like a Cloud Provider. Lots of companies help you do this in your own data centers, from VMWare to IBM and many others. Microsoft's offering in this is based around System Center – they have a “cloud in a box” provisioning system that’s actually pretty slick. The most difficult part of operating a Private Cloud is probably the scale factor. In the case of Windows and SQL Azure, we handle this in multiple ways – and we're happy to share how we do it. It’s not magic, and the algorithms for balancing (like the one we started with called Paxos) are well known. The key is the knowledge, infrastructure and people. Sure, you can do this yourself, and in many cases such as top-secret or private systems, you probably should. But there are times where you should evaluate using Azure or other vendors, or even multiple vendors to spread your risk. All of this should be based on client need, not on what you know how to do already. So congrats on your new role as a “Cloud Provider”. If you have an E-mail system or a database platform, you can just put that right on your resume.

• How to display Sharepoint Data in a Windows Forms Application

  - by Michael M. Bangoy

  In this post I'm going to demonstrate how to retrieve Sharepoint data and display it on a Windows Forms Application. 1. Open Visual Studio 2010 and create a new Project. 2. In the project template select Windows Forms Application. 3. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI. 4. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 5. Open the Form1 in design view and from the Toolbox menu Add a Button, TextBox, Label and DataGridView on the form. 6. Next double click on the Load Button, this will open the code view of the form. Add Using statement to reference the Sharepoint Client Library then create two method for the Load Site Title and LoadList. See below:   using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client;   namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "theurlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void getsitetitle()         {             SP.ClientContext context = new SP.ClientContext(_context);             SP.Web _site = context.Web;             context.Load(_site);             context.ExecuteQuery();             txttitle.Text = _site.Title;             context.Dispose();         }                 private void loadlist()         {             using (SP.ClientContext _clientcontext = new SP.ClientContext(_context))             {                 SP.Web _web = _clientcontext.Web;                 SP.ListCollection _lists = _clientcontext.Web.Lists;                 _clientcontext.Load(_lists);                 _clientcontext.ExecuteQuery();                 DataTable dt = new DataTable();                 DataColumn column;                 DataRow row;                 column = new DataColumn();                 column.DataType = Type.GetType("System.String");                 column.ColumnName = "List Title";                 dt.Columns.Add(column);                 foreach (SP.List listitem in _lists)                 {                     row = dt.NewRow();                     row["List Title"] = listitem.Title;                     dt.Rows.Add(row);                 }                 dataGridView1.DataSource = dt;             }                   }       private void cmdload_Click(object sender, EventArgs e)         {             getsitetitle();             loadlist();          }     } } 7. That’s it. Hit F5 to run the application then click the Load Button. Your screen should like the one below. Hope this helps.

• Where to store front-end data for "object calculator"

  - by Justin Grahn

  I recently have completed a language library that acts as a giant filter for food items, and flows a bit like this :Products -> Recipes -> MenuItems -> Meals and finally, upon submission, creates an Order. I have also completed a database structure that stores all the pertinent information to each class, and seems to fit my needs. The issue I'm having is linking the two. I imagined all of the information being local to each instance of the product, where there exists one backend user who edits and manipulates data, and multiple front end users who select their Meal(s) to create an Order. Ideally, all of the front end users would have all of this information stored locally within the library, and would update the library on startup from a database. How should I go about storing the data so that I can load it into the library every time the user opens the application? Do I package a database onboard and just load and populate every time? The only method I can currently conceive of doing this, even if I only have 500 possible Product objects, would require me to foreach the list for every Product that I need to match to a Recipe and so on and so forth every time I relaunch the program, which seems like a lot of wasteful loading. Here is a general flow of my architecture: Products: public class Product : IPortionable { public Product(string n, uint pNumber = 0) { name = n; productNumber = pNumber; } public string name { get; set; } public uint productNumber { get; set; } } Recipes: public Recipe(string n, decimal yieldAmt, Volume.Unit unit) { name = n; yield = new Volume(yieldAmt, unit); yield.ConvertUnit(); } /// <summary> /// Creates a new ingredient object /// </summary> /// <param name="n">Name</param> /// <param name="yieldAmt">Recipe Yield</param> /// <param name="unit">Unit of Yield</param> public Recipe(string n, decimal yieldAmt, Weight.Unit unit) { name = n; yield = new Weight(yieldAmt, unit); } public Recipe(Recipe r) { name = r.name; yield = r.yield; ingredients = r.ingredients; } public string name { get; set; } public IMeasure yield; public Dictionary<IPortionable, IMeasure> ingredients = new Dictionary<IPortionable,IMeasure>(); MenuItems: public abstract class MenuItem : IScalable { public static string title = null; public string name { get; set; } public decimal maxPortionSize { get; set; } public decimal minPortionSize { get; set; } public Dictionary<IPortionable, IMeasure> ingredients = new Dictionary<IPortionable, IMeasure>(); and Meal: public class Meal { public Meal(int guests) { guestCount = guests; } public int guestCount { get; private set; } //TODO: Make a new MainCourse class that holds pasta and Entree public Dictionary<string, int> counts = new Dictionary<string, int>(){ {MainCourse.title, 0}, {Side.title , 0}, {Appetizer.title, 0} }; public List<MenuItem> items = new List<MenuItem>(); The Database just stores and links each of these basic names and amounts together usings ID's (RecipeID, ProductID and MenuItemID)

• T-SQL (SCD) Slowly Changing Dimension Type 2 using a merge statement

  - by AtulThakor

  Working on stored procedure recently which loads records into a data warehouse I found that the existing record was being expired using an update statement followed by an insert to add the new active record. Playing around with the merge statement you can actually expire the current record and insert a new record within one clean statement. This is how the statement works, we do the normal merge statement to insert a record when there is no match, if we match the record we update the existing record by expiring it and deactivating. At the end of the merge statement we use the output statement to output the staging values for the update,  we wrap the whole merge statement within an insert statement and add new rows for the records which we inserted. I’ve added the full script at the bottom so you can paste it and play around.   1: INSERT INTO ExampleFactUpdate 2: (PolicyID, 3: Status) 4: SELECT -- these columns are returned from the output statement 5: PolicyID, 6: Status 7: FROM 8: ( 9: -- merge statement on unique id in this case Policy_ID 10: MERGE dbo.ExampleFactUpdate dp 11: USING dbo.ExampleStag s 12: ON dp.PolicyID = s.PolicyID 13: WHEN NOT MATCHED THEN -- when we cant match the record we insert a new record record and this is all that happens 14: INSERT (PolicyID,Status) 15: VALUES (s.PolicyID, s.Status) 16: WHEN MATCHED --if it already exists 17: AND ExpiryDate IS NULL -- and the Expiry Date is null 18: THEN 19: UPDATE 20: SET 21: dp.ExpiryDate = getdate(), --we set the expiry on the existing record 22: dp.Active = 0 -- and deactivate the existing record 23: OUTPUT $Action MergeAction, s.PolicyID, s.Status -- the output statement returns a merge action which can 24: ) MergeOutput -- be insert/update/delete, on our example where a record has been updated (or expired in our case 25: WHERE -- we'll filter using a where clause 26: MergeAction = 'Update'; -- here   Complete source for example 1: if OBJECT_ID('ExampleFactUpdate') > 0 2: drop table ExampleFactUpdate 3:  4: Create Table ExampleFactUpdate( 5: ID int identity(1,1), 3: go 6: PolicyID varchar(100), 7: Status varchar(100), 8: EffectiveDate datetime default getdate(), 9: ExpiryDate datetime, 10: Active bit default 1 11: ) 12:  13:  14: insert into ExampleFactUpdate( 15: PolicyID, 16: Status) 17: select 18: 1, 19: 'Live' 20:  21: /*Create Staging Table*/ 22: if OBJECT_ID('ExampleStag') > 0 23: drop table ExampleStag 24: go 25:  26: /*Create example fact table */ 27: Create Table ExampleStag( 28: PolicyID varchar(100), 29: Status varchar(100)) 30:  31: --add some data 32: insert into ExampleStag( 33: PolicyID, 34: Status) 35: select 36: 1, 37: 'Lapsed' 38: union all 39: select 40: 2, 41: 'Quote' 42:  43: select * 44: from ExampleFactUpdate 45:  46: select * 47: from ExampleStag 48:  49:  50: INSERT INTO ExampleFactUpdate 51: (PolicyID, 52: Status) 53: SELECT -- these columns are returned from the output statement 54: PolicyID, 55: Status 56: FROM 57: ( 58: -- merge statement on unique id in this case Policy_ID 59: MERGE dbo.ExampleFactUpdate dp 60: USING dbo.ExampleStag s 61: ON dp.PolicyID = s.PolicyID 62: WHEN NOT MATCHED THEN -- when we cant match the record we insert a new record record and this is all that happens 63: INSERT (PolicyID,Status) 64: VALUES (s.PolicyID, s.Status) 65: WHEN MATCHED --if it already exists 66: AND ExpiryDate IS NULL -- and the Expiry Date is null 67: THEN 68: UPDATE 69: SET 70: dp.ExpiryDate = getdate(), --we set the expiry on the existing record 71: dp.Active = 0 -- and deactivate the existing record 72: OUTPUT $Action MergeAction, s.PolicyID, s.Status -- the output statement returns a merge action which can 73: ) MergeOutput -- be insert/update/delete, on our example where a record has been updated (or expired in our case 74: WHERE -- we'll filter using a where clause 75: MergeAction = 'Update'; -- here 76:  77:  78: select * 79: from ExampleFactUpdate 80:

• Passing data between the VirtualBox Host and the Guest

  - by Fat Bloke

  Here's a good question: "How can you figure out the VM name from within the VM itself?" While this data is not automatically available, the general purpose, and very powerful VirtualBox "GuestProperty" APIs can be used from the host and guest to pass arbitrary data, in key/value pairs format, in and out of the guest. Note that this does require that the VirtualBox Guest Additions have been installed in the guest. To play with this, try using the "VBoxManage" command line on your VirtualBox host machine, and "VBoxControl" in the guest. Host syntax VBoxManage guestproperty get <vmname>|<uuid> <property> [--verbose] VBoxManage guestproperty set <vmname>|<uuid> <property> [<value> [--flags <flags>]] VBoxManage guestproperty enumerate <vmname>|<uuid> [--patterns <patterns>] VBoxManage guestproperty wait <vmname>|<uuid> <patterns> [--timeout <msec>] [--fail-on-timeout]   Guest syntax VBoxControl.exe guestproperty        get <property> [-verbose] VBoxControl.exe guestproperty        set <property> [<value> [-flags <flags>]] VBoxControl.exe guestproperty        enumerate [-patterns <patterns>] VBoxControl.exe guestproperty        wait <patterns>                                      [-timestamp <last timestamp>]                                      [-timeout <timeout in ms>  So to solve our problem above, we set the vm name in the Host system on an arbitrary key like this: $ VBoxManage guestproperty set "Windows 7 (x64)" /MyData/VMname "Windows 7 (x64)" And within the guest we can use: C:\Program Files\Oracle\VirtualBox Guest Additions>VBoxControl.exe guestproperty get /MyData/VMname Oracle VM VirtualBox Guest Additions Command Line Management Interface Version 4.1.14 (C) 2008-2012 Oracle Corporation All rights reserved. Value: Windows 7 (x64) The GuestProperty API is pretty powerful, so for the interested, get more info in the User Manual. - FB

• Server cost for smartphone app with web service

  - by FrankieA

  Hello, I am working on a smartphone application that will require a backend web service - but I have absolutely clueless to how much it will cost. Web Service will handle: - login of users - cataloging of our user base - holding minimal profile information for users (the only binary data is a display picture which will be < 20k each) - performing some very minor calculation/algorithm before return results - All the above will be communicated to server from a smartphone (iPhone/BlackBerry/Android) Bandwidth Requirements: - We want to handle up to 10k users throughout the day. - I predict 10k * 50 HTTP requests a day = 500,000 requests a day * 30 = 15 million requests a month Space Requirements: - Data will be in SQL database. - I predict 1MB/user * 10k = 10GB + overhead. In other words - space is not a big issue. Software Requirements: (unless someone knows an alternative) - Windows Server 2008 + IIS - MSFT SQL Server Note: This is 100% new to me, so please hit me with all you got. Do I need Windows Server or are there alternative? Is it better to get multiple cheap servers to distribute load? Will Amazon S3 work for me? How about Windows Azure? Thank you!!

• WAMP server not starting and a mystery service is using port 80

  - by David Gard

  I'm using WAMP on Windows 7 and tonight I'm unable to start it (it's been working fine for about 3 years previously). I first checked the logs, but nothing in there. So I checked the Windows Event Viewer (eventvwr), where I saw 2x errors for each attempted start - The Apache service named reported the following error: (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80. The Apache service named reported the following error: no listening sockets available, shutting down. After this, I opened the command prompt and ran netstat -a, and to my surprise there were 3 entries for port 80 - Prot   Local Address  Foreign Address   State TCP   127.0.0.1:80       MyPCName:53831   TIME_WAIT TCP   127.0.0.1:80       MyPCName:57834   TIME_WAIT TCP   127.0.0.1:80       MyPCName:57839   TIME_WAIT From here, I'm kind of lost. As far as I can tell, something is utalising port 80, but I don't know what or why. If anyone is able to suggest what I might do next I'd be most greatful. Thanks.

• DB2 Integrity Checks and Exception Tables

  - by imthefirestartr

  I am working on planning a migration of a DB2 8.1 database from a horrible IBM encoding to UTF-8 to support further languages etc. I am encountering an issue that I am stuck on. A few notes on this migration: We are using db2move to export and load the data and db2look to get the details fo the database (tablespaces, tables, keys etc). We found the loading process worked nicely with db2move import, however, the data takes 7 hours to load and this was unacceptable downtime when we actually complete the conversion on the main database. We are now using db2move load, which is much faster as it seems to simply throw the data in without integrity checks. Which leads to my current issue. After completing the db2move load process, several tables are in a check pending state and require integrity checks. Integrity checks are done via the following: set integrity for . immediate checked This works for most tables, however, some tables give an error: DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned: SQL3603N Check data processing through the SET INTEGRITY statement has found integrity violation involving a constraint with name "blah.SQL120124110232400". SQLSTATE=23514 The internets tell me that the solution to this issue is to create an exception table based on the actual table and tell the SET INTEGRITY command to send any exceptions to that table (as below): db2 create table blah_EXCEPTION like blah db2 SET INTEGRITY FOR blah IMMEDIATE CHECKED FOR EXCEPTION IN blah USE blah_EXCEPTION NOW, here is the specific issue I am having! The above forces all the rows with issues to the specified exception table. Well that's just super, buuuuuut I can not lose data in this conversion, its simply unacceptable. The internets and IBM has a vague description of sending the violations to the exception tables and then "dealing with the data" that is in the exception table. Unfortunately, I am not clear what this means and I was hoping that some wise individual knows and could help me out and let me know how I can retrieve this data from these tables and place the data in the original/proper table rather than these exception tables. Let me know if you have any questions. Thanks!

• Can't add service account to domain group during SQL cluster install

  - by Sam

  I'm installing a 2008 instance on a Server 2003 machine which is already running SQL 2005. I need to set up domain groups for the security setup step: http://msdn.microsoft.com/en-us/library/ms179530.aspx On Windows Server 2003, specify domain groups for SQL Server services. All resource permissions are controlled by domain-level groups that include SQL Server service accounts as group members. Much more info on this here: http://support.microsoft.com/kb/910708 I've had problems with being able to add the windows service accounts to the groups at install time. The security admins had to make my account a domain admin - which they were hesitant to do. The account under which SQL Server Setup is running must have permissions to add accounts to the domain groups. Is there a specific security setting which would allow my account to add accounts to a group? UPDATE: I'm looking for specific instructions. I have a global group called domain\servicegroup - what do I tell the security folks to do. I'd love to figure it out myself, but I don't have access to this stuff.

• Why is my cron daemon is being killed every few minutes? OpenVZ?

  - by user113215

  As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({56, 0}, 0x7fffa7184c80) = 0 stat("crontabs", {st_mode=S_IFDIR|S_ISVTX|0730, st_size=4096, ...}) = 0 stat("/etc/crontab", {st_mode=S_IFREG|0644, st_size=1100, ...}) = 0 stat("/etc/cron.d", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 stat("/etc/cron.d/php5", {st_mode=S_IFREG|0644, st_size=475, ...}) = 0 stat("/etc/cron.d/anacron", {st_mode=S_IFREG|0644, st_size=244, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x4036f0, [CHLD], SA_RESTORER|SA_RESTART, 0x2b0e8465f230}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has about 500 MB of free memory, and cat /proc/loadavg returns 0.10 0.21 0.45 so resources shouldn't be the issue. I also tried removing and reinstalling the cron package using apt-get. What else should I check? How do I find out what's killing my crond? Edit: I'm on a virtual machine under OpenVZ (and as such, I have no swap). With cron running, free -m reports: total used free shared buffers cached Mem: 1024 465 558 0 0 0 -/+ buffers/cache: 465 558 Swap: 0 0 0 My OpenVZ User Beancounters via cat /proc/user_beancounters: Version: 2.5 uid resource held maxheld barrier limit failcnt 172087: kmemsize 8275718 25561636 51200000 51200000 0 lockedpages 0 968 2048 2048 0 privvmpages 113442 266465 262200 262200 3740757 shmpages 788 4004 128000 128000 0 dummy 0 0 0 0 0 numproc 39 98 600 600 0 physpages 50521 208434 0 9223372036854775807 0 vmguarpages 0 0 512000 512000 0 oomguarpages 50521 208447 512000 512000 0 numtcpsock 7 323 4096 4096 0 numflock 7 64 2048 2048 0 numpty 1 4 32 32 0 numsiginfo 0 23 1024 1024 0 tcpsndbuf 137984 17878480 20480000 20480000 0 tcprcvbuf 114688 6983504 20480000 20480000 0 othersockbuf 162960 1074440 20480000 20480000 0 dgramrcvbuf 0 24208 10240000 10240000 0 numothersock 101 353 2048 2048 0 dcachesize 459171 747444 10240000 10240000 0 numfile 1010 4221 50000 50000 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 39 424 2048 2048 0

• How to install service packs onto Thin Apps and other questions

  - by Buzlightyear

  I have a VM that I use to do all my ThinApps, Once I have done my application and its built I copy just the bin folder to a server which has a share, I then create a shortcut to the program exe on users desktops. This all seems to work ok. Firstly is this correct? If so, how then do I apply a service pack to that application after the ThinApp VM has been reverted to a base image, I have corel draw which i have a service pack for but it wont intall it as its saying it cant find the package installed on the computer. I have Thinreg batch file so have included corel into that and the program appears in the program list. I have the sandbox redirected to the server share mentioned earlier into seperate user folders when the user logs in. Obvisouly once i have done a App I revert to a previous snapshop so my thinapp vm is back to base image, so the corel install is lost. Sorry if im missing something very simple. Is its a case if you have an exe/msp you have to reinstall the whole app again and start over, Thanks for any help.

• Do you need to advertise an AFP service via Avahi for an Ubuntu Server to show up in OSX Finder?

  - by James

  I am only advertising an NFS share plus the "model", and I don't want to install extra services on the Server unless I have to, ie netatalk, as it is used solely for NFS exports. Currently there is no entry in Finder under "Shared" with below config of Avahi. serveradmin@FILESERVER:/etc/avahi/services$ cat nfs.service <?xml version="1.0" standalone='no'?><!--*-nxml-*--> <!DOCTYPE service-group SYSTEM "avahi-service.dtd"> <service-group> <name replace-wildcards="yes">%h</name> <service> <type>_nfs._tcp</type> <port>2049</port> <txt-record>path=/Volumes/StoragePool</txt-record> </service> <service> <type>_device-info._tcp</type> <port>0</port> <txt-record>model=Xserve</txt-record> </service> </service-group> Server: Ubuntu 12.04.01 x64 Clients: OSX 10.6.8 , 10.7.5, 10.8.2 The goal is to advertise that NFS share, then assign a really old Model code of Mac like a Powermac and switch out the icon for a more "LinuxServer-y" one. Plus allow users to connect to NFS in a manner they are familiar with like our other Xserve servers. I think Avahi is working in general as if I do: nfs://FILESERVER.local/Volumes/StoragePool it will connect fine. Any ideas?

• Exchange 2010 SP2 Not Allowing Logon for Users with Expired Passwords

  - by JJ.

  When we provision users we set the "User must change password at next logon" flag and instruct them to go to OWA to login for the first time and change their password. Using the registry setting ChangeExpiredPasswordEnabled as explained here: http://technet.microsoft.com/en-us/library/bb684904.aspx worked well prior to SP2 installation. This allows users with 'expired' passwords to logon and forces a password change before they can access OWA. We just installed Exchange 2010 Service Pack 2 and now it's no longer working. Users with this flag set ('expired' passwords) can't login in at all unless we clear the flag. FYI here's the registry key configuration as set now with SP2 installed: Any suggestions as to how I might fix this? Or did MS break this feature in Service Pack 2?

• How to copy files from HDD to HDD with integrity checking

  - by RafaelM

  I am moving data from an almost dead HDD to an external USB drive using linux , because for some reason Windows cannot see the data. I want to copy a large amount of data over from the HDD to the USB drive with integrity checking. I thought about copying everything over and then checking with md5summer but this would take a reaally long time because its a lot of data and this is not a very powerful PC. What tool can use to do this on Linux?

• Slow Network Performance with Windows Server 2008 SP1

  - by Axeva

  I recently installed Service Pack 1 for Windows Server 2008. Since that time, network performance has been awful. Both Windows 7 and Mac Snow Leopard clients have seen miserable speeds when trying to read or write to the server. This is the exact update: Windows Server 2008 R2 Service Pack 1 x64 Edition (KB976932) It's a very simple file server setup. No Domain or Active Directory. Essentially just shared folders. It's Windows Web Server that I'm running. Are there any settings I can tweak? Should I roll back the update (doesn't seem wise)? Update: I've turned off the Power Management for the Network Adapter. That may help. If it doesn't have to be powered on at the start of a request, it should speed things up. Or so I would assume.

• Suggestions for sharing and using data between Ubuntu and Windows 7 dual boot

  - by wizjany

  Note: TL;DR, scroll to bottom for summary. I recently set up my computer for a dual boot between Ubuntu 9.10 and Windows 7. My current drive setup is as follows. | A1 | A2 | | B1 | B2 | B3 | A1: 100 mb, windows 7 "System Reserved" boot partition A2: 230 gb, data section, this one needs to be shared between the operating systems B1: 125 gb, windows 7 OS B2: 123 gb, ubuntu OS B3: 2gb, linux swap space Pretty much i want to have my documents, music, pictures, videos, etc accessible from both operating systems. My first attempt involved making the data (a2) partition NTFS, and moving my home folder from ubuntu to the data partition. However, as I read NTFS does not work nice with permission, and it messed up my home folder. My next idea is one of the following: 1) format the data partition to ext2/3/4 and move my home folder from linux there, and get a driver to read ext partitions in windows 7. The problem with that is that most of the ext drivers/software are not compatible with windows 7 or do not integrate with windows explorer (I really don't want to open a separate software window just to access my data, plus it's probably not compatible with other software.) http://www.fs-driver.org/ looks promising, but I'm not sure how it works with ext4 and windows 7 (not officially supported, when trying in vista compatibility mode, it tells me I need to format the ext drive to use it). My next idea, 2) keep the home folder in ubuntu where it is, but create symlinks for the Documents, Music, etc folders to an NTFS formatted Data (A2) partition, and add those locations to the windows 7 libraries. I'm not totally sure how the permissions would work out, but it should be fine since it's only the documents, music, etc and not the important config files in the rest of /home/user/. Correct me if I'm wrong. Currently, symlinks is my best idea, although i'm not sure how it will work. Any suggestions, additions to my ideas, links, pointers, whatever would be greatly appreciated. Even if it means i should reformat both my drives and repartition (2 250gb drives if you want to suggest a setup for that), I won't be too opposed if that's the best suggestion (I've gone through the format/install/format/reinstall process 5 times over the past 3 days, once more won't hurt me). TL;DR, summary: I have two hard drives. One is partitioned for Ubuntu and Windows 7, the second one I want accessible to both operating systems to store documents, music, pictures, videos, etc. Suggestions on how to set up the data drive please =) P.S. bonus if I can get an apache server document root folder working between the two OS's as well (permissions could become very complicated, so don't worry too much about that) P.P.S. Related question, but data viewing is one way: http://superuser.com/questions/84586/partition-scheme-and-size-for-dual-boot-windows-7-and-ubuntu-9-10-with-separate-p

• Wireless network unavailable, no networks found after Windows update

  - by jacobsee

  Old Dell Inspiron 8200 laptop with Linksys Wireless G network adapter card (WPC54G v2). Wireless connection was working fine. Then I ran a bunch of windows updates, I think the last one was the recent .NET 3.5 service pack update. Now wireless networks won't connect. Using windows to manage wireless, no networks show up. I'm typing right now on another laptop where wireless is working fine. I've restarted router & Dell laptop several times. Tried to Repair wireless connection and refresh network list. Also restarted DHCP and WZC service, all to no avail. I then uninstalled .NET 3.5 SP (don't remember number) and .NET 3.0 SP2. I don't remember all the windows updates that I just ran because I haven't used this laptop in a while so had to catch up on some updates.

• Error setting up Blackberry Internet Service with Outlook Web Access

  - by Travis

  I'm trying to set up Blackberry Internet Service to connect to our Windows SBS2003 outlook web access. I've tried every possible combination of credentials by I always get the same error: An error occured during email account validation. Please check your information and try again. If the error persists please contact your System Administrator. The fields are the following: Outlook Web Access URL: http://mail.domain.com/exchange (I've also tried just using the IP address http://000.000.000.000/exchange with no effect). User Name: JohnDoe (same as OWA login / domain username - I've also tried DOMAIN\JohnDoe) Email Address: [email protected] Mailbox Name: This one confused me a little bit, but it seems it should be the same as the domain username (eg. JohnDoe). I've also tried DOMAIN\JohnDoe, and a number of other things. No matter what I do, I get the same error message. At this point, I'm basically just trying things, because I don't really know how this service is supposed to work. Does anyone know what causes this particularly vague error message, and what I can change either in my email settings or on our exchange server to resolve this?

• Web Service gets unavailable after several concurrent calls

  - by Roman

  We are testing GoDaddy Virtual Data Center and came to a very strange issue when our web site gets unavailable. GoDaddy Support keeps saying the issue is in our web server settings, but looking at the result of our tests I doubt it. TEST ENVIRONMENT Virtual DataCenter with Windows hosted at GoDaddy.com. All servers have Windows Server 2008 R2 Datacenter, IIS 7. Server One with IP address 10.1.0.4 Server Two with IP address 10.1.0.3 Both servers are in private network not visible from outside. Port Forward with IP address 50.62.13.174. Port Forward is assigned to Server One TEST DESCRIPTION JMeter is used as a Client App to simulate 30 concurrent users sending 100 SOAP requests each. Interval between requests is 1 second. Http link used for testing: http://50.62.13.174/v2/webservices.asmx TEST ONE Test is run from a computer in our office. After JMeter starts running test, almost immediately, the link above becomes unavailable in a browser. After test completion, the link is not available in a browser for about 5 more minutes. Remote Desktop is working well, so we can connect to Server One remotely. After about 5 minutes since test completion, the link becomes available in a browser again. TEST TWO Test is run from Server Two (that is part of our virtual data center). Test works very well, no visible delays in processing. The link is available in a browser all the time. TEST THREE Test is run from Server One using localhost. The result is the same as in TEST TWO - no issues. TEST FOUR We repeated TEST ONE from other computers that we have located in different countries, all with the same result as TEST ONE. CONCLUSION As the test works well from Server Two, but does not work from outside our virtual data center, we feel there are issues with the network or its capacity. The whole behaviour looks like out requests from outside get stuck somewhere before reaching our virtual data center. Has anybody had similar issues in the past? Are there chances that something is wrong with our server settings?
