I installed DB2 Express 10.1 on my Windows 7 (64bit) notebook. Now after the installation finished I cannot connect to the database. During the installation I specified "C:\Daten\db\db2" as the directory to be used for DB2.

When trying to connect, I get the following error:

> 
> SQL1031N The database directory cannot be found on the indicated file system.
> 
> 
> 

However the database seems to be there: 

```
db2 => connect to db2inst
SQL1031N  The database directory cannot be found on the indicated file system.
SQLSTATE=58031

db2 => list database directory

 System Database Directory

 Number of entries in the directory = 1

Database 1 entry:

 Database alias                       = DB2INST
 Database name                        = DB2INST
 Local database directory             = C:\Daten\db\db2\IBM\DB2\DB2INST
 Database release level               = f.00
 Comment                              =
 Directory entry type                 = Indirect
 Catalog database partition number    = -1
 Alternate server hostname            =
 Alternate server port number         =

```

I verified that the file system privileges are correct for the directory (the user running the DB2 service has full control on that directory and I made him the owner as well).

The content of `C:\Daten\db\db2\` looks like this:

```

\---IBM
    \---DB2
        \---DB2INST
            +---cfg
            +---cfgcache
            +---DB2
            |   +---ctrl
            |   +---hmonCache
            |   |   \---DB2
            |   |       \---0

            |   +---spmlog
            |   |   \---SPMLOGSD
            |   +---SQLDBDIR
            |   +---TMP
            |   \---UIF
            +---DB2DAS00
            |   +---cfg
            |   +---dump
            |   +---log
            |   +---metadata
            |   \---tmp
            |       +---dastmp
            |       \---schedtmp
            +---db2dump
            +---function
            |   \---unfenced
            \---license

```

I then tried to re-catalog the database:

```

db2 => uncatalog database db2inst
DB20000I  The UNCATALOG DATABASE command completed successfully.
DB21056W  Directory changes may not be effective until the directory cache is
refreshed.
db2 => catalog database db2inst on "c:\Daten\db\db2\IBM\DB2\DB2INST\"
DB20000I  The CATALOG DATABASE command completed successfully.
DB21056W  Directory changes may not be effective until the directory cache is
refreshed.

```

But that didn't help either.

For some reason it seems DB2 can't access the (existing) directory: 

```

db2 => list db directory on "c:\Daten\db\db2\IBM\DB2\DB2INST\"
SQL1031N  The database directory cannot be found on the indicated file system.
SQLSTATE=58031
db2 => list database directory

```

I'm not experience with DB2 and the last time I installed Express everything went smoothly, so I'm a bit lost now.
